I had 2 chicken snakes in my hen house with 2 of my broody hens got rid of the snakes and had to move 1 of my hens I put her back on the clutch she was sitting on. I think she abandoned them they were almost fully developed she hasn't been back on them for 3 days it is around 80 degrees during the day and 60 to 70 at night should I keep the eggs and see if they will hatch or is it to late.
