I went to get feed today & there was a sign Chickens $10.00 RR & PR mix. I went to look a saw 75+ birds in a 10x10 dog run. Their beaks were all short I asked why and was told it keeps them from pecking each other. What's up with that I've never seen it before & the poor girls now look like ducks. I brought 2 home. Will it grow back? can they forage OK? Does it hurt? Anything I should do special for them? I also brought a cochin bantam with no feathers on her head What can I do for her?
