Chickadee Nest/Wren Guard Help!

4 years ago

I have a Black-Capped Chickadee that just laid six eggs in the nest box in my backyard. I just put up a House Wren guard (L-shaped metal taped to pieces of cardboard) to the front. There is about 2 inches of space between the hole and the cardboard.

The mother chickadee tried to get in multiple times, maybe 6 tries, and then finally got in. When she left, she again tried to enter, and it still took her 5 tries, which took about 10 minutes. Should I be worried that the mother won’t be able to enter in the future? Or should she be able to, now that’s she’s gotten in before?

I’m wondering if it’s worth it to have the wren guard or if I should remove it. What do you think?
