We're in Maine and have had one heck of a fall! Just this week we finally breached single digits. My lilacs were budding, Geese are flying south, etc. However my concern, is just now two of my hens look very disheveled and unkempt. Is there a chance they are picking on each other or are they molting? I'm concerned that now we have 2 degree weather and two are bald in spots! I thought this was seasonal in in the late summer? Shoudl I be concerned? We do not have a heated coop, its insulated and kept free of drafts in the winter. Most of my hens are only 8 months old but these two are older rescued birds so unsure of ages, at least 1 year. They were laying when I got them this summer. Thanks!
