The vaccine should come with a diluent. Only use the diluent that comes with your vaccine. The amount of diluent you need depends on the vaccine you will be giving your chickens. Follow the instructions that come with the vaccine to properly measure and mix the diluent. Gently lift either wing, pulling it out to its full extent. Expose the underside of the wing so that it is facing up and the web is visible. Gently pluck a small patch of the feathers on the wing web so that you can properly administer the vaccine. Sterilize this area using a cotton ball dipped in rubbing alcohol. It may be helpful to have a second person stabilize the chicken and extend the wing while you administer the vaccine. The wing web is located near the bone where the wing connects to the body. Your vaccine should come with a 2-prong needle called a wing web applicator. Dip the applicator wells into the vaccine bottle. Take caution that the needle is not dipped too deep. It should be just enough to fully submerge the applicator wells. If you need additional wing web applicators in case of failed vaccine administration, you can get these from your vet or the vaccine manufacturer. Once the applicator has been loaded with the vaccine, pierce the needles into the wing web, taking care to avoid feathers, bones, and large blood vessels. You can ensure proper placement of the applicator by centering the needle puncture in the middle of the triangle formed by the spread apart wing web. If you accidentally hit a blood vessel, load a clean needle and repeat the vaccination process. Otherwise, replace the needle after every 500 birds. Check for scabbing or scarring in the wing web 7-10 days after vaccination. Scabs are an indicator that the vaccination was successful. If scabs are not present, consult with your vet to see if another dose of vaccines should be administered.

Using a screwdriver or wrench, loosen up the screws or nuts securing the overhead garage tracks. Depending on which part of the tracks you need to adjust, this may mean the fasteners closest to the door, furthest from the door, or both. If you're trying to fix misaligned tracks, shift the tracks left or right until they are perpendicular with the vertical tracks. If you're trying to slow down the speed at which your garage door opens, simply raise the tracks up. When you're finished adjusting the tracks, the distance between them and the garage door should be .5 inches (1.3cm), otherwise the door may stick. Using your fingers, tighten the nuts or screws holding the overhead tracks in place. When you can't tighten the fasteners by hand anymore, grab your screwdriver or wrench and turn the fasteners 2 or 3 more times. This will help you prevent unwanted stripping while tightening the fasteners to a safe and secure degree. Open and close the garage door multiple times to make sure it works as expected. In particular, check that the horizontal tracks can support the door while it is in the overhead position. While testing, do not stand underneath the door in case it malfunctions.

Find a place where you will be able to consistently work and study without distractions. If you plan to do classwork at home, make sure that you will not be distracted by family members or roommates while you're working. Cafes and coffee shops usually have consistent Internet access. Check with the owner to make sure that you are able to occupy a table for extended amounts of time. Libraries are a good option if you prefer to work in a quiet space. Many have desktop computers available for your use, which is helpful if you do not have a laptop. Many public parks offer free wifi. You may find it relaxing to study in the park, as long as there are no distractions nearby. As soon as you receive the course syllabus, write down the due dates for any important assignments, papers, and exams. Many online courses require online assignment submissions to be made by a certain time. If each weekly assignment is due at 5pm on Sunday, make sure to note this specific time so you can keep your assignment submissions organized. Use a paper planer or online calendar to keep all of your assignment dates organized and accessible. If you are taking more than one course at a time, create a master list that has each of your course assignment due dates listed. Each week, organize your schedule and make a priority list for assignments that are due that week. A study schedule will help you to stay organized as you progress through the course, and will help you manage your time efficiently. Be as detailed as possible in your schedule. Plan ahead and take in to account any outside commitments that you've made like vacations or doctors visits that will disrupt your normal schedule. Use the list of assignment due dates that you wrote down at the beginning of the course to set aside time to study for large exams and to complete projects or papers. Stick to the schedule that you set for yourself. You will need to follow your schedule to accomplish your coursework on time. Create weekly to-do lists that map out your assignment deadlines and required coursework. Take detailed notes for each of your class readings and lectures either by hand or in an online document. Be prepared to take notes during each online lecture. Organized and detailed notes will be your best study tools to prepare for exams. It can be tempting to zone out or not pay attention during online lectures since you aren't physically in a classroom, but taking notes can help you to avoid this temptation. Keep your notes in a centralized and organized space. If you take notes by hand, dedicate a large notebook or binder to holding all of your notes. If you take notes on your laptop, create an online file to hold all of your notes in one place. Your online course will have specific deadlines for assignments, just as any other class would. Always meet these deadlines and produce your best work on assignments. Online courses are great for independent learners since you are held accountable for your ability to follow a syllabus and meet deadlines outside of a physical classroom. You must reliably meet deadlines and turn in your work on time. Missing deadlines can have a large negative impact on your grade. Plan ahead if you know that you have a busy week coming up so you won't have to struggle to get your work done.
