Hi! I am new to chickens (have ducks and Guineas). I have a bantam hen that has lost all her feathers on her chest. She seems to be the only chicken loosing feathers (at least this many). Her chest is completely bald all they way under her body. She is trying to set on eggs even though I clear them out regulary, probably getting ready to go broody on me, but I have to solve the feather loss first. Any suggestions? Thank You.
