She would be about a year and a half (give or take we got her at about 8 weeks old on the 3rd of June last year). I haven’t checked for mites but they are let out to free range during the day and they have a large coop and access to a run during the day. I will check her over for mites. What kind of mites am I looking for? Red mite or other types?
I will do this tonight thanks. I was going to grab her and check before I left for school but she was laying so I left her alone.Looks like something grabbed a mouthful.
I don't think that's from bugs, but.......
My Bug Check notes:
Have you checked them over real well for mites and/or lice?
Google images of lice/mites and their eggs before the inspection so you'll know what you're looking for.
Part the feathers right down to the skin around vent, head/neck and under wings.
Best done well after dark with a strong flashlight/headlight, easier to 'catch' bird and also to check for the mites that live in structure and only come out at night to feed off roosting birds.
Wipe a white paper towel along the underside of roost to look for red smears(smashed well fed mites).
Good post about mite ID by Lady McCamley:
Hen peck do you think or maybe moulting?
It's spring where @Butterscotchbitesfinger lives, so molting is not likely.One of my chickens has lost a lot of her neck feathers because of molting.
