So I noticed a couple of things with my flock today. Two of my 3 Welsummers have issues. My top hen, Audrey, was sitting alone, puffed up and NOT running to the scratch I threw out--VERY strange. She is normally very pushy and aggressive. So I picked her up only to feel a very large, HARD ball where her crop is. First thought: impacted crop. I checked the other girls to make sure what I was feeling was abnormal and it was. Okay that's one issue that I have identified. But I'm having a hard time with the second one and this is the one I need help with. All of my chickens are 9 or 8 months old. We had an insane summer (temps in the high 90's to low 100's) and now have an abnormally cold winter. I've noticed A LOT of feathers in the coop but only one girl looks like she's losing feathers (the second Welsummer). I caught a glance of her feathers being blown by the wind and saw there wasn't much there. So I looked at her more closely and saw that her face was missing feathers and the area under her chin. I looked at the bases of the feathers, around the vent, neck, under wings and around face, I cannot see anything! No bugs, no egg sacs. Can she be molting at such a young age?? ETA: I noticed pin feathers around the face and neck. Is this normal? Thanks for any input.
