I'm the same way! I made a DIY incubator out of a 10 gallon aquarium because I had all of the materials for it, so it seemed like a better deal than spending money on one. Well, I wonder now, because I my temperatures kept fluctuating quite a bit the first couple of days. Last night was the first night I was able to let myself sleep without freaking out about it and checking on them every little while. My husband says I'm pickier than a broody mother hen.. Oops!
I'm just so excited and want to make sure that everything is OK. I'm already calling them chicks, even though they don't look remotely anything like chicks at this stage!
I am just hatching out some "mutts". Some are going to be half silver laced wyandottes and some will be half black sexlinks. My rooster that I believe to be the father of all of them is a New Hampsire bantam mutt. It'll be interesting to see what comes out of it. I have some eggs that are pinkish white and others that are light brown. The brown ones are more difficult to candle than the white ones, but since they're a lighter brown color, it's not too bad. What kind of eggs are you hatching?
