My chooks are just a year old and i noticed one of them was looking a bit bare around her neck and assumed she was moulting. I checked her over and she was also moulting from her underbelly. I checked my other two hens and they are moulting from their underbellies too but no where else. Ive read that hens have an order in which they moult but mine arent following this. Is there something more sinister going on or are they just moulting in their own way!?
