I'm not going to worry about it, since the birds are eating them. I think they are enjoying their diet today. I'll just have to buy a new bag much sooner than I had expected (hoped).
If it had been teenagers, it would be one thing. But, we're talking about little kids who have never been around chickens before. My 8-year-old daughter should have known better than to get the bag of worms out for them to play with - so she's more at fault. The other kids would have never known where to look for meal worms. Believe me, she and I had a discussion about it this morning and knows that if it ever happens again, she will be doing chores to replace the bag. I have a feeling they got to being silly and just threw the worms into the air for the fun of it.
