I have ten hens that were hatched in April of this year. Three Dominiques, three Silver Laced Wyandottes, three Buffs, and an Americauna. This morning I went out to feed and saw one of my Dominques has this going on with her neck and head. These are my first Chickens ever so I if it is an issue I want to get it under control before it effects any of the others. From what I have read they are kind of young to be molting. They have more space than what is recommended for a coop or run. No changes in diet. They all seem to be laying well. Any ideas? Thanks for your help.
