I have two laying hens that are "broody" and no roosters but the problem is that they both want the same nesting box although there are two other nesting boxes. Both hens have decided to sit in the same nesting box together. This has been going on for a couple of days now and how long will this last. I have been taking the eggs from them daily and the one gets a little feisty and fluffs her feathers and growls the other day she even put her head around the eggs because she didn't want me to take them. How do I get them to use the other nests? How long does this activity last?
