We have our first momma hen. She is a year old sex-link(Nubby) from last years 4-h pullet chain. We slipped her some fertilized eggs and she hatched out one adorable Favorelle (it's sibblings are happy out of the incubator and in the brooder box). We have her and the chick isolated in a seperate pen as her flock mates were not nice to the tiny new addition. The chick is about three (3) weeks old now. I have noticed alot of feathers in Nubby's pen. Is it time for her to molt? Is she doing it early because of the brooding stress? Or is there something wrong? Any advice would be appreciated.
