A while is all I can say. If you want to do a science experiment, put some water in the oven at 105* Get the water to 101*, then time it to see how much longer it takes to react.How long does it take a temp spike to affect embryos? Yesterday (day 15 for chickens and ducks) the bator was at 105.6. It had been having trouble holding temp so I had half of it under a blanket overnight. I candled just now and I lost one chicken egg for sure, maybe two, but all the ducks are still kicking.
Looks nice. I am too afraid to use my metal shed though. Consider how hot a car gets even in the shade with the windows cracked.[COLOR=B42000] [/COLOR] this is the new shed I'm working on, opted for a metal vrs building a wood one, tied it in with the back run, inside running wire screen around the bottom and up the sides to keep out critters, gotta think out the flooring, the fans I'm gonna order will help keep heat an humidity down
