Don't know, I've always have left my broody hens alone.10/24 are hatched in 24 hours under the broody and she's still on the nest. So assuming it can be spread out over more than 24 hours?
Good Luck!LOCKDOWN UPDATE!
Day 20: I have easter eggers and Ameracaunas(lots of internal pips and 1 external!)
Day 19: 4 Gamefowl eggs looking fantastic, 1 iffy but I left it in just in case.
Day 18: 4 Crested Creme Legbars and 6 Bielefelder eggs.
I waited until now for lockdown as I have a staggered hatch and wanted to wait till the Legbars and Bielefelders hit day 18.
Day 10: 3 Modern Game Bantams that have just been moved under a broody! I moved them with a broody to prevent them from going into "lockdown" along with the rest. I hope it won't be a problem when they hatch in half the normal incubation time!
Anxiously waiting on my hatch that should start today. Checked eggs at noon and no pips yet. I went out to till up the garden, came back after an hour and had 3 hatched! Waiting on the rest now!!
Congratulations! I hope you get more soon.
