Hello... this is a little chick we adopted. I don't know what breed or gender it is, but it is about a month old. S/he has been healthy until 2 days ago, and stopped wandering around with the others. She seemed to have an injured foot/feet, (fairly symmetrical) but there appears to be no injury. Her legs are not paralyzed, but she walks poorly, wobbly, without balance, uses her wings and her beak to balance, and with her whole tarsometatarsus flat on the ground, rather than just her foot. She isn't worsening, but isn't improving. Her poop is normal, and her appetite is decent. She wasn't vaccinated at birth, but from what I've read of Mareks, this doesn't match up real well... Any ideas?
