when does the 21 day start for chicken eggs to be incubated when they go in to the incubator or when they are layed
Hi Jeremy,
The hen eggs will start to incubate once all the eggs have been laid and the hen starts to sit in earnest or you put the eggs in an incubator.
Hope that helps.
Just to let you know that I have set up a free forum with a section on hens. http://farmingfriends.com/forums/forum.php?id=8
