2 days in an incubator. The hen has been sitting for about 2 weeks. She's free range. The babies would never make it. So I wanted to save a few and raise them.
So that would make 16 days they have been incubated (14 hen + 2 incubator)
I'm afraid after that amount of time therewas still only yolk nothing was going to develop in the egg.
Have you cracked a few test eggs open to check for fertility?
