Thanks, Julie – no 6th egg yet but have not spotted mama going in to incubate – maybe later this afternoon. Yes, 5 eggs is not too common but usually 4 is what most lay – but different locations make a difference, also. Yeah, that wren hasn’t gotten the idea yet (yeah!) – this morning I checked the box and it was almost half full of sticks, which I promptly took out at least half. I ALMOST feel sorry for the little thing – it is working so hard, but they shouldn’t be so mean to our precious bluebirds (throwing eggs on the ground or pecking a hole in them – have had this happen a FEW times, actually probably before I knew about a wren guard or didn’t get one on in time.
