First time hatching and one of my EE/Cochin babies hatched this morning and I notice there is like a wash of blood inside the shell and a little bit on the chick. The chick hasn’t really “fluffed up” but the daddy is a frizzle so it’s possible that’s just the way it’s “fluff” is going to look? Just wanting to make sure there isn’t something I should be doing about the blood. Also, how long can I leave the chick in the incubator safely? I want to put as little stress on the little one as possible!
