I have a flock of 9 hens . . . 5 who hatched in the Spring of 2013. They are Black Australorps and Buff Orpingtons and they all molted for the first time between November and December. I also have a Salmon Favorelle from 2013 who has also recently molted. This year, I raised an EE, a barred rock, and a SFH chick, hatched in Feb. The SFH has new feathers coming in all over her head and neck and molting! shes not even a year old; Is this normal????
