Well, my hatch isn't going as well as the last one.
Long story shortened, on day 18, I had 4 lavender orpingtons and 6 golden sebrights. I knew 2 of the GS were questionable, but left them in. I could tell by day 20 they were goners. 1 lavender hatched without problem. Next lavender made a huge hole, but wouldn't spin. First sebright zipped 3/4 of the way and stalled. So I pulled each of those out and assisted, and they are fine. Finally another sebright started zipping and made it all the way around, but didn't push the cap off. Then I could tell it was stuck, so I had to help that one too. Then a 3rd lavender pipped.. on the wrong end... through a blood vessel! Andother sebright had internally pipped on day 20, but I couldn't see movement yesterday. Pulled it this morning and its DIS, as is another one, I think. When I left home this morning, 2 lavenders and 2 sebrights were out, with the wrong-end pipper still going. I think the rest are gone.
I need to recheck my hygrometers. I think it was too dry, even though the readings were fine, and I was using the exact setup as I did last time, as far as sponges and channels. Membranes were really crispy. I swear, I still think it had to do with switching from heating to air conditioning in the house, mid-incubation. :/
