I have a broody who is now on day 23. So far nothing has hatched. Yesterday there was an egg that looked like it had been sat on too hard and had cracked. I peeled a tiny piece of shell back (I know I shouldn't have!) and there is a chick in there. I brought it in and put it in the incubator because this is the third egg this has happened to. The other 2 chicks died so I didn't want to chance it with another one. How do I know if the chick is even alive? Should I be concerned that there is a little piece of the membrane exposed? Should I be doing anything more than keeping the temp and humidity up? Thanks!
