Well at least your yard is bug free!! If you go to Petco they sell live mealy worms- you could lay them on the porch- lol ease the parents job. But then again I think swallows catch flying bugs so they won't know what to do with them!
It always amazes me how swallow babies stay in the nest!!
@Jpgurl:
I feel like they're in a very iffy spot. I really hope they don't plop out. I'm not sure what my dogs would do! 4951
