So i have a two or three bald chickens and one in particular has a very red butt. now i have 24 chickens, 10 of which were mostly all bald this summer when i got them and more than half of those have now grown feathers in the fall. the rest were day old chicks i got this spring. they are all very healhty happy birds and fully fluffed up. the guy i got the chickens from said the older hens picked their feathers out during the winter. so now im worried that my new chicks will do the same this winter, how can i prevent this? and what could my older hens have that makes their arses all red??
