I have a broody that has been setting on an empty nest (well, I empty it every day, lol, usually three or four "broody" eggs, which I consider dog food) and would be happy to slide a dozen under her. She has hatched eggs for me before, marans, so I'm sure she can hatch some silkeis. My silkies ... I don't keep records, sorry to say, They are old enough to have spikey feathers sticking out of their topknots. I could go back and see when my auction ended, count three week from then, and that is when they hatched...
