One if my BR girls squatted in front of me, so I bent down and picked her up. Well, she fussed a lot and scrunched herself up in my arms, and then fluid started coming out of her mouth. I'm wondering if that could happen if she put pressure on her crop when she scrunched up, or do I need to worry that she's sick? What types of illness can cause fluid to come out of her mouth? She seems fine otherwise, except she may have leg mites. I was trying to look more closely when she started wiggling around in my arms.
