I myself have been trying to hatch seramas. I have my own breeders so I have the eggs but am having a hard time getting them to hatch. My first try, I set 7 eggs, 1 died around day 10 and the 2nd hatched but died 12 hours later. My 2nd batch, I set 12 eggs, some of my own and some I bought. 2 died around day 10, some were infertile, and 3 made it to lockdown. Out of the 3, 2 hatched on their own and the 3rd died in the shell. Fully formed but never pipped. The last set, I set 5 eggs, all 5 were fertile. 1 died around day 15, and the other 4 made it to lockdown. 1 died in the shell, I think it drowned because the air cell was too small. The other air cells looked good, but only one hatched and I had to assist. The other 2 died in the shell, fully formed. I think I could have saved them if I would have only assisted a little earlier. I am nervous since I now have 20 more growing in the bator on day 16. I have learned something with each hatch though. I realize that I will have to assist and am prepared to do so. I find that if the bator humidity stays 30-40% until day 18, the air cells do well. I think my issue has been my temps. I have been using a LG 9300 still air and the temp is uneven through out. I ordered a fan so we will see if that helps. I think mine have been too wet and become glued where they cannot move to pip due to low temps.
