It is ok..... check the temps often.... I just lost my last hatch all 18 babies. My thermostat blew and the temps reached 113* and killed them ALL!
Poor babies..... I have also had a bulb blow TWICE in the brooder with the previous batch and lost 2 babies.... this has not been a good week...
We replaced the thermostat today and I will be testing all weekend before I put more eggs in the hatcher. AND not only will I have plenty of extra bulbs, I am going to put another light with a thermostat so if the temps drop too much it will come on and maybe save some babies next time.
DON'T get paranoid because of what happened to me, it really was just a fluke. I think hubby would let me put all my eggs in the incubator now lol
