I noticed today that my bantam frizzle Cochin has thinning in her flight feathers. I checked her out good and don’t see any parasites. Do I need to be concerned about this? She is 21 weeks and just started laying a week ago (6 eggs in 8 days!), she it the first one to lay in the flock, I don’t know if that has anything to do with it. I haven’t seen any behavior changes in any of them (other than the egg laying lol) or seen her or another mess with her wing feathers like that so I don’t know what is going on.
