I have a broody hen that was sitting on 5 eggs. She is in the coop in her own pen. I must not have closed the door right on her pen, and another hen got in with her, there must have been a bit of a fight and 2 of the eggs were broken. The eggs she has left have yolk and straw stuck to them. Can I or should I clean them. I candled them and can see veining so at this point they are growing.
