Ok so first off sorry for the lack of answer here bc i know when i have a question what i really want its an answer BUT just wanted to say that i'm dealing with the same thing and wondering the same thing!
One cinnamon queen hen, will be a year this summer, best layer and has been laying all through the winter when other hens quit, suddenly is acting off. Just a little bit...off. Not always with her rooster and hen-mate and the other day didn't go into the coop at dusk with everyone.
I noticed she is losing some feathers too? Right above the tail is where i'm seeing the most noticeable loss of feathers. Its not down to the skin, just the down is exposed. . I am also unsure if its molting or something else??? I brought her in today when i found her laying down in the run when everyone else was in the coop
She is still laying and eating (ate some grapes i gave her anyhow and her crop was full). Her poo looks runny though and more yellow than i'm used to? I dunno either, i'm not sure if this is a normal molting time or if theres something else i should be concerned about? Anyone have any advice? The flock is able to free range everyday from about 1 to dusk and provided layer feed, water (duh), oyster shell and treats on occasion (strawberry tops, grapes, dried mealworms, etc.)
I'd love to hear if anyone has an opinion or advice about my hen, I really don't want to lose her! She doesn't have any other symptoms that i can see (no foul smells, no watery eyes/nose, no cough)
