I put thirteen eggs in my incubator and only three hatched. I opened the eggs on the 25 day and 1 chick died on like day 19 it had everything developed and part of the yolk was absorbed. then another was probably like 16. then there were a lot that died on like day 10 or so with only a little devoloped. I was turning them 3 times a day and the temp stayed at 99-100 and the humididty was 40-55 then 60-70 on lockdown. What did i do wrong?
