As some of y’all know we are incubating some eggs that were missed during daily gathering. We are at day 18 right now. I messed up and had the temp higher than it should be the first few days. Tonight while candling, one egg appeared to have a bill sticking in the air sack. Could the high temp to start with make them hatch a week early ? Should I lock down on day 23 instead of 26 ? All air sacks are getting bigger every day. The possible fathers are K/C or runner. The hens are K/C, and Rouen.
