I have seen this many many times. Most often I just trust the broody that there was something wrong with the chick. But I have seen where one hatched really early and the hen kills it. Then is absolutely perfect with the new chicks when they hatch on time. Again I am trusting the broody. If she gets off of the nest to care for one chick she loses all of the rest of the growing chicks.I am so behind- I've been super busy for the past two weeks, and you know how fast this thread moves!
Anyway, I have a question. My broody was due to hatch in the next few days. I don't know if I can't count or what because this happened to me last time, but I got a chick today. Anyway, that's not my question- when I found this chick, it looked dead and was too the side, so I thought it had died so she had pushed it out of the nest. But then I noticed it was breathing, and that the side of the head was bloody. So I picked it up and looked at it and it cheeped. When I tried to put it back into the nest she pecked it. I took it and put it in the brooder under heat, but I don't know if it will make it, the head was pretty beat up and I don't know how long it was cold. Should I be worried about her doing that to the rest of the chicks? One of the eggs at least (I only looked for like 1/2 a second) is pipped, but who knows how long it will take the rest to hatch.
So at the moment I'm camped out right outside her nest box watching. It's going to be a long couple days. Needless to say, if she pecks the next chick her leg band is getting changed from "broody" to "cull." But is this something that she did because there was something wrong with the chick, or do hens just do this sometime? I guess a hen attacking her own naturally hatched chicks never occurred to me. Any advice or experience would be appreciated.
I always trust the broody. Chickens survived thousands of years without human interaction. IMESHO all we humans done is weaken chickens. Making them too relient on people. So I raise mine the way it would have been done 100 or more years ago.
