Set the eggs like you normally do. It is very hard to figure out air cell development from the charts. The shape of the egg makes a big difference and since the air cell bends down, the ones that look small may be bigger than you think. Weighing is the best way to go.I'm going to ask here since it seems people are here. My eggs that I set for this HAL all have very different air cells. Some have to big and some are to small... I only have one bator and one hatcher. Idk what to do. Some still have loose air cells so they are hats to handle. I would use my hatcher as a bator but I just moved the chicken eggs to it since they are due on Friday but some are tiny badmen eggs and seem like they will come on day 18 or so... Any advice please?
Have a great hatch!
Oh, wait...that happens a couple times per week.

That was super fast! How long should I let them sit before putting them in the bator? I want to try to hatch all of them if possible and I only have 4, so I want to do everything right. Also, my class is really excited about the chicks hatching this week. I felt like such an amature talking to them about hatch expectations and how long it might take for the chicks to get out of the shells. I think I'm more of a wreck than they are. I have a student on "peep patrol" sitting next to the bator. My principal came and asked me if she could take a few home- that was awesome!!
