I have a silver spangled hamburg. She's a fantastic layer, even though I got her at over two years old. She's also my escape artist. A great chicken though, and I'm thrilled with her.
Silly, when I put my babies outside, I have a "time out corner" in the coop. It's blocked off by chicken wire so the other birds can't get in, but they can see the chicks. I have a light in there for the first bit. Eventually, I set them free, but make sure there's places for the babies to hide. I got Sundance's broody and chicks from her around April 22. I just released them to general population last night. The primary reason I waited so long was I wanted the babies to be big enough to 1- not escape through the chain link and 2- be a little less vulnerable to the other chickens.
Last night, I attempted to move my broody hen because her nest box is 3' off the ground. She seemed unsettled, but eventually sat back down on her eggs. This mornin g I went outside, and she was wandering around, and eggs didn't even feel warm. I hurried them into the incubator. After they were warmed up, I candled. Saw movement in one of the legbar eggs. The rest seemed iffy. Supposed to hatch tonight or tomorrow. I stuck her back with the other chickens and she went right back to that nest box. Silly bird. I guess I'll see if these guys hatch. If so, I'll put her back in the leper colony with the babies. If not, I'll try to break her. The five eggs I have are: 2 fbcm, 2 legbar, and one 1/4lav am, 1/4 fbcm and 1/2 legbar (offspring of the broody).
