Wed nite we put sulphur powder around the base of our three birdboxes
Two are bluebirds and had eggs in them
We saw the next morning the door was unlatched and door was totally open like a landing zone and eggs gone
The other bird box was not open but eggs were gone same nite
One is on a pvc pipe
Other one on a tree
We have had four sets of blue birds
Every year to live
Any idea what did this
We have one nest of wrens and worried for them
So sad to see blue bird parents looking for their eggs
And or babies
Something ate the four babies two weeks ago
Never had that happen in twenty years here at our home
Ideas
Advice
What can we do to protect the boxes yet allow the parents in and out
Snake prevention
we are using sulphur powder at base of tree or pvc pipe base
