my silkie has been slowly losing feathers on her chest and each week it gets worse and worse. i asked about it a few weeks ago and people thought it might be a broody patch were she plucks out the feathers. the problem is she started laying a few months ago and hasn't been fully broody yet. sometimes i see a few feathers in her nest but thats all. i also notice her crop seems to look a bit large and round like a golf ball this morning when i let them out. maybe its just because i never really saw a chickens crop without the feathers but it was the morning so she could have eaten much? do you think this could be caused from mites, just her picking the feathers out or something else? i also noticed when she bends over you can see her vent and before it would be covered with feathers/=. i dont kow if that means anything or if it because she has started laying? i not sure if i should post this under here or under predators and pest?
