My poor hen has been sitting on this egg trying to hatch it. Ive been making sure she eats and everything. The stupid other birds kicked her off her egg and broke her egg and ate the baby!!! She must have fought like crazy to protect her egg. I feel horrible for her . Why would they do this and how can i stop it from happening again? She was nesting on the floor of the coop. Should i have put her in a nest box?
