The two hens that are laying eggs (Gloria and Hazel) have decided to go broody in the same nest box. Then they switched to the corner of the henhouse. I can understand hazel going broody, but Gloria is a red sex link, and broodyness is bred out of them.
Yes, normally Sex Links don't often go broody, but it can happen. Nice to have to hens that get along so well that they share the same box! If they are setting on fertile eggs, sometimes two birds can break the eggs. So just be aware of this situation. Good luck with these two broodies!
