Momma Bluebird decided to go for a third batch and layed egg number one today. It is June in Texas which means it will be getting hot so I had to step up the original heat shield. After researching the Bluebird Nut Cafe archives we decided that styrofoam could be the best solution to this heat problem. We zip tied the shields to the current, thin shields. Hopefully the styrofoam will hold up well and that the doldrums of summer can hold off for a little while longer.
