That happens, I thought I was a hatching mavin at one time. Then the anti-hatching demons found me.My last hatch was 100%. Next hatch looks like 5 of7, on infertile, one questionable. This group was 4 cayugas and 3 geese. Threw the Cayuga out the morning, infertile. Two geese developing, one questionable. I thought I was a hatching maven but have been seriously humbled.
