Lockdown question and hatching tips wanted

[pefferlawchicken]

Ok i set 12 eggs in 2 different batches , they are only 1 day appart and i wondering when i lock down tommorow can i lock the laters ones down a day early ?? will it harm them , also anyone got any good tips , i really hope my eggs hatch i have had a few bad batches but my incubator was bleeched and cleaned well befor i put them in and everything looks good , 99.5 F through incubation with about 33 % humidity
also should i turn down them temp , when hatching, becase they way i think of it , the chicks are big and have been moving around generating their own heat that may get to hot in the shell?

anyways any suggestions would help

thanks

Leave the heat at 99.5 through the hatch. The brooder can be at 90 to 95.

Yeah, you can lock down the second group a day early. I added a couple extra eggs a day late and they did fine locking down with the rest.. they just hatched a day later.
