I took on incubating chickens for my FFA chapter. i candled on day 7 and there was 4 out of 14 eggs. Then on day 15 and there was 3. wasn’t bad compared to our first batch that accidentally got cooked. i can’t candled again on day 18 and just looked like blobs. all was good. removed from turner and increased humidity and it got up to 82% so i had to open up incubator to get it down.day 20 i didn’t see any movement. How do i hear chirping? humidity is down now to 63%. Now it’s day 21 and no pipping as i can see. i’m patiently waiting the arrival of the chick-a-peas. Any help? did i do something wrong?
