I was reading the Lancaster Farming classified last week, and there were 20 hole rollaway nest boxes for sale. I called Monday and they were all sold. However the guy asked me what i was looking for, and I told him. He said that he had a ten whole in the garage and would I want that. I said yep, and went to get it today. He charged me 10.00 for a nice looking 10 hole metal rollaway nest box! Yeah!
