I don't count the day hatched so 10'ish days after that. If
you are ready sure it's wonderful but pull at night only.
About 9'ish is good. Do a bit of a snuggle and put in
brooder. This gives the crop all night to empty from parent
fed foods and they are ready for handfeeding starting about
7 am. 7, 11, 3, 7, 11 for a few days...
I pull each one according to hatch date so they are taken
Wishing you well,
