I put 12 eggs under my broody at 11:30am on March 31st. I calculated Day 21 to be Wed April 20th. But it is now Fri and no chicks. When should I give up hope of those eggs and place some bought chicks under her? We did have some chaos during her setting. An opossum was in the main house so even after he was gone the main flock was wary of it and didn't want to go in for a few nights. My co-owner put them in Broody's coop and it seems as if 4 eggs may have been damaged, they are just gone. I don't want to get chicks and then have her abandon eggs that could still be viable. They are Cream Legbar mixes. What do all you wise, experienced chicken folk have to tell an only 2nd time broody chicken mama?
Thanks in advance,
