If baby chicks continue to pick, try putting just a pinch of salt on their feed. This may also help deter them. Increase waterers to one 5 gallon fount per 100 chicks. Install roosts at back of hrooder. Prevent water puddles around founts.
Chicks can range outside on warm, sunny days, but only if clean range is available.
Then mix some of this extra sweet water with some of your feed to make a soupy mix. Give your chicks this special feed and water mix for 3 to 4 days to get them over the effects of shipping. Sometimes the stress of shipping causes the manure to stick to the back of the chick. It is important to remove this daily. Pull off gently.
