I had a broody hen who was sitting in eggs that are supposed to hatch in about 2 weeks. Today I went out to check in her and she was roaming the yard clucking and making a lot of noise and I figured she was just off the nest so I went to check to see if she had stolen more eggs. Well another hen was sitting on the eggs that she had been sitting on. So there are two hens trying to hatch out 1 set off 11 eggs. Is this normal? What should I do?
