So when I set all my eggs in the home made incubator I kind of put in a variety just to see what happened. I seriously didn't expect even one hatch. I had planned at the end if they didn't hatch I would dissolve the shell and make a morbid gift of preserved fetal chickens for a friend (she likes stuff like that). One of the eggs I included was a double yolk, it wqs just a "can this be done" thing. It was more a test of how precise you need to be to get a hatch and can I hatch eggs with less than $20 in materials instead of buying a $100 incubator. Well we have two baby chicks hatched! And hopes for more on the way. One of the twins pipped! Unfortunately a rather large piece of she'll broke off when it did and the membrane is exposed. It still has blood in it, so I turned the egg so it wasn't directly under the light and raised the humidity, and dabbed. Little water on the membrane. These little guys are going to need help. I'm giving them until I get home from work in 14 hours from now to make more progress on their own and absorb their blood and yolks. Any advice.for helping these little guys? I read that the one on the wrong end of the egg would need help pipping, but thays the one that pipped first! It's beak is free and clear.
