I had some questions on how to hatch some chicks for a class room. I'm not the teacher but it was already attempted and none of the 24 eggs hatched. Someone said they werent fertilized, they had been shipped to the teacher so that may have had something to do with it also. I told the teacher that if she wants to try it again i can get some of my dad's eggs for her, i know they'll be fertilized at least because this spring the same chicken's eggs were incubated and they hatched. The problem is, he lives hours away and i don't know the first thing about hatching eggs in an incubator. If someone could answer a few questions or give me some tips it would really help us out and make a lot of 6th grade kids happy. They all were pretty upset after waiting 21 days to find out they didn't have any chicks. Once an egg is laid how long before it has to get into the incubator? Does an egg, once its laid, have to stay a certain temp? If so what is it? Can an egg go several days before it gets into an incubator? What is the best way to get a bunch of eggs hours away from its incubator to the incubator? Any other suggestions or tips would help, thanks!
