Ok so Ill plan to lock down tomorrow night. The other issue is I have to travel to NY early Sat morning until Sunday Mid day for a dog show. Of course Sat is day 21. So unfortunately if anything goes wrong I will not be here to do anything about it. My kids and hubby will be here and I may be able to give them advice over the phone but... Im hoping if they hatch on Sat they will be fine to just stay in the incubator until I return on Sunday. Thoughts? Now I hope they dont hatch on Friday. If they do hatch say late on Friday will they be ok in the incubator until Sunday morning or should I move them to brooder early Sat morning before I leave for NY...Such bad timing on my part. I was so excited to get my eggs in the bator that I didn't look ahead and realize I had a huge dog show this weekend, Im so dumb!
They can survive off of the absorbed yolk for up to 72 hours, in nature this gives the rest of the chicks time to hatch under a broody hen until she gets up to start tending to them. So yes, they would be ok for an extra day. I would keep the room they're in darker if you plan to do that, to reduce any pecking of hatch mates while they're trying to figure everything out.
I personally like to take them out as soon as I can though...maybe if you have the brooder warmed up and ready then your husband can just move them over once they're done hatching?
