I have 2 hens that have hatched 2 chicks each. However they were neglecting those chicks waiting for the rest of the eggs to hatch. They never did. I removed the eggs, candled and moved the broodies off the nest. I had to put chicks in brooder because the mommas wouldn't leave the nest. Now a week later the hens still won't leave the nest, even though I have tried everything suggested here on BYC. Come to find out DD#1 has slipped 3 eggs under each hen, to the detriment of DH's Father's Day cheesecake. (Had to wait for more eggs). How long can they last like this??? Will they sit forever? Now I have to wait 19 more days.
