Symptoms of coccidiosis are lethargy, hunching, poor appetite, and runny droppings with mucus or blood. Corid is the treatment. Does she move her neck normally, up and around? There are skeletal deformities that can cause spinal abnormalities.
I read a lot about coccidiosis, but her poop looks completely normal! Would it harm her to do a round of Corid just in case?
She can stretch her neck out, but doesn't often. When I had her in our chick box yesterday, she would stretch out and peek out over the top, and when she did, she almost looked normal! Unfortunately, that is not her normal stance. Considering how short her little body is compared to her siblings, we really think it is a deformity. While in our brooder box, she was always just a hair smaller than the rest, but it really started being prevalent when they were about 2 months old. The rest shot up and she just didn't. She stayed short and ball like.
