This is my first time raising chickens so bear with me if this is a dumb question. Okay my 26 chickens are 9 weeks and very healthy. There is no evidence of picking and none of them are "missing" feathers anywhere thats evident. In just the past few weeks (its been HOT here as everywhere) I've noticed ALOT of feathers on the floor of the coop. Are they just shedding some? Is this normal? Is it because they are hot or do they just lose feathers naturally? Thanks for any help.
