We are trying to graft 3 chicks to a broody. We rec'd the chicks from the hatchery yesterday. Last night, I tried to put them under her. All looked well. I stayed up until about 3 am watching. When I got up at 7am, 2 were not under her, huddled in a corner. The 3rd was still under her, but when ever it came out, she "pecked" at it until it went back under. I had no choice in leaving for several hours today, so I put all 3 chicks in a brooder. I am thinking that I will try again tonight. Mama is still trying to sit. Do mamas usually peck at their chicks to get them back under them? Or should I give up on this?
