How long before eggs under broody hen are too late to pull for my incubator?

[cchardwick]

I've been collecting eggs every other day and I have a broody hen that sits on the eggs every once in awhile, she drives me crazy. I'm wondering if she sits on the eggs for a day and a half if it's too late to pull them and save them for my incubator. I'm trying to save up enough storing them in the basement until I have enough to fill up my incubator, but I'm afraid that if I pull the ones from under the broody hen that they may have started developing and that sitting at room temp for a few days may kill them. Is that right? Should I be worried about this? Or can I steal her eggs and keep them at room temp, then set them in my incubator a few days later?

I think that the eggs might get rotten and not hatch i'm not to sure though

It depends on the temperature. I've had a on again, off again broody sit and not sit on a nest full of eggs. They actually hatched! They took forever though, the last one took about 6 weeks from when she started and most of the chicks didn't make it. The air temperature (it was a hot summer) and the hen sitting at night was enough. Would not repeat that though!
