A couple years ago I took the roof off my BB box and replaced it with piece of wood with a hole drilled in it and covered the wood with plexi-glass. My husband accused me of trying to cook the BBs. He said all it would do is generate heat inside the box and cook the birds’ eggs. So I took it off and put the original roof back on the box. What is your thought on the plexi-glass retaining too much heat in the box?
I was wandering if there’s a chance one of the babies that fledged from my box last year would come back this year to lay his/her eggs with a mate? Don’t last year’s babies nest later in the year?
