I have a 1 year old silkie (who is broody if that means anything) I force her to free range once a day and all she does the whole time is either scratch at her head or take dirt baths like crazy. Should I be concerned that she has them? I am not familiar with them at all.... I have tried to look for them but those dang silkie feathers are so hard to look through! I looked under her wings because I read that is a good place to look but didnt see anything. I just wonder with the ways she has been acting. And she scratches her head pretty hard and a few times in a matter of 5-10 min.
