we have 11 under mamma and 1 piped. we had a close call with one last night. he hatched too close to the outside under the hen. we found him still partway in the shell . he was cold wet and unresponsive. we brought him in and warmed him up over the open stove door. after we got him to peeping and moveing we stuck him in the bator for about an hour. took him 10 min to start to peep. he's back with mamma now.
went out this morning and saw 3 little yellow heads poking out from under mamma's breast. may get some pics later.
Glad you found him in time.
