Yes Deanie. Not a dumb question. You want to keep the HOSPs out of the box, and the Chickadee hole is too small for them. I don't know that a hole reducer would keep a House Wren out though. You may not have them in your yard. I had never ever laid eyes upon one until last summer. On May 1st, I had one show up in my yard. It went from box to box, filling each one with sticks. They are like the HOSPs in that they will destroy eggs and nests of other cavity nesters. They do not look or sound like our sweet Carolina Wrens.~Angie

i was reading this thread with interest. i have a situation where it appears i have 8 bluebirds who have hatched in one nest (thursday may 2, they were born). it may be 9, it's hard to tell. while monitoring the nest in late april i noticed what appeared to be eggs missing from the 3 that had been laid earlier in that week. the reality was that the eggs had been pushed down deeper into the nest and covered with pine straw. the mother kept coming back (may have been another species coming in and covering the egg with straw? i have seen no house sparrows here at all) and eventually she started laying again. turns out, there were 10 eggs total in this nest when she was done! i guess five from the first attempt and 5 after that. bottom line, 8 babies are in there now. i'm putting out meal worms twice a day and making sure there's lots of water nearby in the bird bath, and plenty of shelled sunflower seeds for the parents nearby in that feeder. anyone ever seen or heard of a situation like this?

Hi! A couple weeks ago we noticed 2 Carolina wrens building their nest in our fern right outside of our kitchen window. We were so excited! Then a few days ago we no longer saw them around and sadly thought that they had abandoned their nest. This morning we were talking about removing the nest from the fern and when I peeked, I saw 5 eggs! Now we are concerned if they have abandoned their eggs :( Is this possible? We haven't seen them around at all. What time of the day do they incubate? Would it be possible that we are missing their timing? We are not morning risers. Agh! I'd be so sad if by any chance we scared them away :( We have been very respectful, however sometimes we would open the window. I do not know how long the eggs have been there. I thought that as soon as they were close to being done building their nest, they had left. Do they first build and then lay their eggs? Thank you so much!

I would wait and see which one they lay eggs in.
