This is my first attempt at incubating chicken eggs. I have2 incubators, a Hovabator with automatic turners and a Little Giant still air for the hatcher. Currently I have 8 BCM on day 22 with no pipping, and some assorted Cubalaya at day 21. One on the Cubalaya pipped and was pecking and chirping last night, but was dead when I got home from work this afternoon. I broke open the shell and it was fully developed. The hatcher is at 65-75% humidity, but has had some temp variations (97-107 on 2 different occasions) since they were placed at day 18. Now the hatcher has a bad odor. So.....Do I assume the rest of the eggs are goners, or do I wait another couple of days. I've read as much as I can find, but still made some mistakes (obviously).Any advise is appreciated. I have moved the incubators to a more stable ambient environment so the temp variations should not continue to be a problem. WHAT DO I DO NOW?????
