We're getting fertile eggs now, pretty sure Marans roo is doing all the work. Most of the eggs are from our Hamburg and dark Brahma, though our welsummer just plopped one out in front of us earlier today.
Anyone know how quickly the eggs become unviable when it's this cold?
What I have been told is that is the egg gets below 45 F or so, it become unviable. I haven't run any tests to check this though.
