Yep, it sure does...I still have them in the nests, spreads the love......and some times I move them around, just to see what happens.Unblocked the nesting boxes today and the birds are still sleeping on the roost when I checked this evening. Does the golf ball in the nesting box thing work? My birds still aren't laying and I'm expecting they will soon, though I didn't know their age when I bought them.
