I have a newly hatched baby chick that has membrane on it. What do I do? Leave it? It is on the top of its head and a wing. Then it has a long "string" hanging off its bobo. Will this correct itself or do I need to step in? It is completely out of the shell and running around with the other chicks that hatched out. The other chicks are pecking at the "string" but it does not seem to be dislodging.
