Welcome Lori – wow – to have a nest & 2 eggs already is amazing. But since you live near Austin, TX you would have much warmer weather than a lot of us. I remember well my very first bluebird nest & eggs (this is my 9th season), so know how thrilled you must be. If your box is made to BB specifications (especially with good roof overhang on all sides & drainage holes), you should be okay. Here in mid-Missouri we are also supposed to get rain all week long and it did downpour yesterday. However, my pair have not built their nest yet, but have picked their box. Others will chime in here about wet nests – I know this is NOT good for babies but am not sure about just eggs??
First thing to do I imagine is to look inside box & check if nest is wet. Good luck.
