our 1 12 week old bantam x chicken seems to be paralyzed. she doesn't seem to be able to stand up much and when she does, she tries to balance with her wings, but still topples over and lays down most of the time. she eats, but not much. we are new backyard chicken keepers and got the 4 chicks from a local petshop. this chick has feathers growing upwards too. Anyone know what could be the matter?
