Q: This will require a little research on the particular breed of your ducks. Heavy breeds such as the Muscovy and other meat production breeds will usually have a ratio of one drake to five ducks maximum. Lighter breeds such as the Khaki Campbell and Indian Runner can have a maximum ratio of around one drake to ten ducks. Keeping too many drakes with too few females can cause injury to the females as they can be mated too often. If you are attempting to cross breed, be careful about the size difference between the drake and ducks because this can also potentially cause injury. If you have too many drakes you can keep them in a separate pen during the breeding season. You can mate ducks as a pair if you choose. The problem comes when there are multiple drakes and not enough space and females. You should mate young animals to keep the generation interval low and achieve the greatest genetic progress. First-year drakes and ducks are best for breeding but do not mate birds younger than 6 months old. While some domestic ducks will mate year-round, the typical mating season goes from late winter through spring to early summer. This is the most likely time that your ducks will show mating behavior and lay eggs. Mating behavior will include head bobbing, pecking, neck biting and attempts at mounting by the male. Ducks will typically mate with any other duck including those of different breeds. If you want to create particular crosses you must keep breeds separate that you do not want mixed in. If you do not want your ducks mixing and you have multiple breeds then you should separate them during breeding season. Muscovy ducks that mate with another domestic ducks will produce mule ducks. Mule ducks are sterile but can be good meat producers. Mixes between other domestic ducks will not be sterile. This will depend on the number of ducklings you want to produce. For most breeds, one duck can produce around 100 marketable ducklings per season. You will get better results when you have less birds being mated and housed together. However, commercial breeders will have to have mass mating for economic reasons.
A: Keep the correct ratio of drakes (males) to ducks. Minimize the time between generations. Know the mating season. Watch for mixing breeds. Calculate the number of birds to be mated.

Article: Below is how you would start a new session; you would need to include this on every page you want to access the sessions, use it instead of session_start();Starting a session: require('session.class.php'); $session = new session(); // Set to true if using https $session->start_session('_s', false); $_SESSION['something'] = 'A value.'; echo $_SESSION['something'];
Question: What is a summary of what this article is about?
Using sessions with the custom session manager.

Problem: Article: You can use either a yoga mat or a gymnastics mat, but you want a mat that is going to provide some support to your head and neck and necessary cushion for comfort. Lay your mat lengthwise in front of you. If you are a complete beginner to doing headstands, you can place your mat up against the base of a wall and practice your headstand with the support of the wall. Practicing your headstand against a wall will help you figure out the different areas in your body that you need to flex and balance to hold a headstand.
Summary: Position your cushioned mat.

Q: Use a time-tracking computer app, such as Rescue Time, to understand how you're spending your time online. You might be losing a lot of hours you could be studying chatting with guys. Keep track of your time to make sure you're spending enough time on your schoolwork. An hourly study target can help you sideline boy distractions. Consult your planner and prioritize the assignments for the coming week. Use the distraction-free time when everyone else is consumed with a party to get a head start on the most difficult tasks. Doing this will make your school week easier, as you'll have gotten the most difficult work out of the way. In the evenings, take 5 minutes to set an academic goal for the next day. It may be reading 3 chapters of your history lesson, understanding a hard math problem, or talking with your teacher about your writing skills. Naming a concrete thing you'd like to achieve keeps your attention focused on the goal rather than on boys. It may help to write your goal down in your day planner to keep it at the top of your mind. You can refer back to it when you're feeling distracted. While setting small goals can keep you going from day to day, you need a bigger purpose to keep you motivated about school. Whether you'll be the first in your family to attend college or you have a particular job in mind, think about some long-term achievements your studies are building towards. Staying connected to your dreams will make it easier to ignore the background drama of boys, dances, and crushes. Focusing on school is easier when you know you'll get a break to indulge in your boy-craziness occasionally. You might reward yourself with social time when you hit an academic goal. Find a way of being social that works for you and helps you achieve balance with your studies. For example, you might make a deal with yourself that you can go to a dance if you finish your social studies paper early. You may even work harder on your paper because you really want to go to the dance. Remember that most high school relationships don't last. While it may feel like focusing on your studies takes you out of some social loop, what you learn in school is way more enduring and useful than any boy could be to you.
A:
Track how you spend your time for more balance. Plan for the week ahead on the weekend instead of going to parties. Set a goal for school every day. Set long-term goals to stay motivated. Set aside time to be social.
