I have a broody hen that has hatched a couple chicks but she favors the oldest (by 2 days). The one she pecked in the head is 3 days old now and I had to separate her because i noticed the hen wasn't letting her eat. What can i put on the other chicks wound, the hole is just behind her eye. Also, should i remove the older chick as well? I was planning on separating any of the other ones if they hatch.
