This is my second hatch and the first time I got 21 chicks to hatch out of 38 fertile eggs. This time I only ended up with 17 that made it to lock down out of 30 fertile. Yesterday morning I could hear some peeps and see some rocking slightly but today absolutely nothing. Today is day 22. I know they can go late a couple of days and I have had a lot of trouble maintaining the temp since lockdown. It concerns me that I could hear/see life yesterday but not today. Any thoughts?
