I have 7 rir hens and 1 rir roo. One of my hens is bloody and has been sitting on the eggs of all 7 hens. I am not able to touch any of the eggs bc if I do she will break them all. How am I supposed to know if she will hatch any out? I have grabbed a couple that she nocked out of her nest. And they pad the water test and from what I can see there is nothing in them. How long till they hatch?
