Last spring, my husband and I bought chicks and built a coop and started our own family of chickens. We have 2 Rhode Island Red hens and one RIR rooster and 4 Plymouth Rock hens. Anyway, we want to see if we can get chicks from our eggs and, being a high school Biology teacher, I wanted to make it a classroom project. My question is, what are the major concerns with incubating and hatching eggs in the classroom? What equipment is absolutely essential? Will the fact that I'm not at school on the weekend make this difficult to pull off? Approximately how long will it take to incubate and hatch the eggs? Again, I'm a total newbie and I have NO CLUE what to do. I just started my research, but I figured a more direct route to get answers to my questions would be helpful. Thank you!
