I have been trying to find out why my hens will not lay in their nesting boxes and after many methods have found that the nesting boxes are too small! I bought them from meyer hatchery and don't want to buy new ones and don't want them going to waste. I have 5 Isa Browns, 1 Australorp, 1 Silver Laced Wyandotte, 4 Welsummers, and 1 buff orpington. How can I make it so they can fit? They have been laying in the corner of their stall in the barn and it doesn't seem to be private and something keeps eating their eggs through the little crack. Help!
