I'm trying a separate hatcher for the first time. I'm using an old Hoverbator that I've incubated lots of eggs in over the years. This year, with a cabinet incubator I didn't think I'd ever use that old one again, but I decide to try it. Plus, this week I finally overran my ability to hatch all I can incubate. I just put 74 eggs into lockdown ! They don't all fit well into the bottom of the big incubator.
I'm trying to run the separate hatcher at a high humidity (70+ RH) and slightly lower temp (targeting 98.5). That comes from Porter's website for hatching turkeys, but I think it's probably good for chickens too. Chicks contribute their own heat in the last few days and I want to make sure the temps don't spike too high in that little incubator.
The turning racks sure look empty now, only 30 eggs left there, but that will change this weekend, I'm getting over 100 eggs to set this week (thanks in part to wingstone and blarneyeggs). Fortunately over half of both sets get immediately handed off to a friend that I am hatching for, so I don't have to raise them all.
