I have two mutt girls that have gone through a light molt and I thought they would be too young for that this year. Checked them out again today for any signs of mites etc., nothing that I could detect. So does it depend on the chicken when nature decides it's time for them to molt? New feather shafts are coming in, one is a bit cranky, but they seem perfectly fine otherwise. Tail feathers and neck feathers seem to be the ones that have dropped thinned out..should I get the microscope out and look harder for crawly things?
