Ok, I have another question: I have 10, 3 month old reds and 7 nesting boxes. is there a reason they only use 3 out of the 7? it's the same 3 boxes. All of the boxes are nice an clean soft straw nothing blocking the way. Some roost at night, on the roost and the others roost on the edge of the nest and some lay in it. will they eventually no what to do and where to go?
