I have week ago rhode island reds, 5 total. 4 are in great shape, one is obviously hurt, not putting any weight on one leg, The chick can move are hopping and using her wings and is same size as others, so she is eating and drinking. Should I put that chick in a seperate box? I have another heat lamp etc. its more whether to keep them together and possibly let the 4 healthy chicks run over the hurt one or seperate them, not sure if the lone chick will like being alone. Thanks for any input.
