This allows the birds to rest and should help the livability without affecting the growth rate. When you do this you must have enough feeder space so all birds can eat comfortably at one time. Continue to pull the feeders at night until you are off of chick starter at approximately 3 to 4 weeks. You can now begin leaving the feeders in for longer periods of time. Once you take the brooding lamps away at night you no longer need to pull the feeders.
Birds require good ventilation without drafts in order to perform properly.
Always try to provide ventilation high up on the walls to prevent any drafts on the birds at floor level. Be sure birds do not become chilled at night or overheated. This will bring on a condition called ascites and can cause severe mortality from four weeks of age on. If you live in an area with a high amount of sodium in the well water, try to provide water from another source. Refer to the approximate growth and feed consumption chart that should be a guide to you.
