Hello - our 1.5 y/o Gold Laced Wyandotte has some very irritated-looking skin & several bald spots. She is eating & drinking as normal, & we don't believe her egg production has been affected. We suspected mites as 2 others in our flock have varying degrees of this but we haven't found evidence of this after examining the chickens & the coop nor have we found bullying to be the culprit. We initially chalked it up to molting but her appearance has not improved since winter. We are relatively new chicken owners & appreciate any advice!
