Okay, so I broke a rule.
I don't believe in helping breeder chicks hatch. I think you are taking vigor out of your flock if you do. I don't mind if it is a layer, or a meat bird, but not with a breeder.
My Easter hatch went well. They started piping on Friday morning, early, and by Saturday afternoon I moved the chicks to the brooder. I always try to leave unhatched eggs in the bator for a few days in case I have some late hatchers. I needed the hatcher cleaned out for another batch, so on Sunday evening, I took an unhatched egg out of the bator and just as it was about to be tossed, I heard a faint peep. It is from my breeders, but I just couldn't stand it. I candled to find the air cell and opened a hole. The chick had internally pipped, the membrane looked good but the chick was not moving. To make a long story short, I stayed up till 2am working the little booger out, thinking the whole time that I would end up culling it because it wouldn't help at all. Whenever I touched it, the chick would peep, sometimes loudly, but it wouldn't try to get out. It never kicked, it never pecked, it just sat there waiting for me to get it out. I finally was able to free it from the shell. The yolk was fully absorbed, it was sticky, but the bird was well formed, physically. It was a bit "mushy" but otherwise looked good. I gave it a bit of physical therapy (gently stretched it's neck, wings, legs, etc.) and some PolyViSol. I put it in a cup with it's legs under it and left it in the bator. When I got up Monday morning, the chick was out of the cup and walking around the bator! I moved it to the brooder and if it weren't for the blue food coloring I put on it's back, I wouldn't be able to tell it from the others. Now, I still won't use it for breeding, but I have to admit that I am glad that I didn't toss the little darling.
What the heck, I guess I'm just an old softy, afterall...........
