I have two chicks out of their shells and another pipped. They are in a tiny Brinsea incubator with 7 eggs. It's very crowded. They are climbing all over the other eggs and now I see blood near the foot of one chick. Could it have cut itself? Should I remove them? It is probably quite obvious that this is my first hatch. . .and I am a nervous mother hen by nature. I was planning to keep the chicks in for at least 24 hours so as not to mess up the humidity for others, but maybe I should take them out? The first one hatched fully about 4 hours ago. Thank you for any advice!
