Right ZZ's I'm through hatching also. I just finished hatching out a doz welsummers, six black/coppers, a doz golden cuckoo's and ten black austrolorps. Now ZZ's I have a question, I left the eggturner going all during the hatch and it didn't seem to matter, they all hatched except two. I didn't do it on purpose I just forgot to take it out. I know you had a hovabator and I wondered if you had ever done that. I was shocked when I realized they were still turning. Have you ever done that?
