My pullets are about 20 weeks now. This is my first chicken experience so I do not know what is normal as far as how many feathers chickens lose on any given day. I presume just as we lose hair daily, they must lose feathers. I have 14 birds and there seems to be an awful lot of feathers in the yard. None of the birds look like they are in any kind of molt or shedding disaster. Is it normal to have lots of feathers in the coop?
