I Have 12 baby chicks from eggs one broody hen sat on. She abandoned the last 5 eggs after the first 7 hatched. We brought the 5 inside and figured out 2 where no gos but the last 3 we were able to hatch in our brooder. I tried to sneak the first of the three to hatch to the mom but she pecked both eyes bloody the next day. I have been able to nurse the baby back to good shape and they are now 3 days old. I had another hen go broody about 4-5 days ago. Is it to soon to slip them under her. All hens and chicks are in the main coop with 14 hens no rooster but the broody with the 7 babies is behind a partition and I would do the same for the new mom. The new broody has been sitting on golf balls so far. If the new mom hasn't been sitting long enough to be tricked I am going to attempt to add the 3 to the original 7 in a couple days.
