I'm probably being paranoid, but I have a question about my little girl. I had her and my male outside today and to my happiness she took a bath in her water bowl! when she was wet and fluffy I noticed a large nickel-dime sized bald spot where her vent is (I had to lay down on the ground so I was under her bottom to see it) and she was fluffing up the feathers around her butt with her foot. when she is not fluffy you cannot see the spot and she is acting normally otherwise, is this something I should be concerned about?
