Worms in chicken run

[ashley22]

I have 3 eight week old chicks. We live in Las Vegas and right now it is very hot. I put in a little water tray for them to dip their feet in when it's hot, recently when I went to refill the tray I noticed little worms underneath the tray. They kind of looked like mealworms or maybe even maggots? They soil and straw was obviously wet under the tray. I cleaned it out immediately but am worried that the chickens have been eating them. Should I be worried if they eat them?!
Sorry if I'm posting this in the wrong place. First post ever.

I had some what I think were centipedes that liked to hang out beneath my water container for my flock also. I moved it and put some fresh cut grass clippings/leaves under it and I haven't found any since (it hasn't been a long time though) or you could try putting it on a piece of wood. Also my hens ate the bugs and they are doing fine.

Now that I have researched more I am pretty sure they are maggots.
I have been wetting the run to help them deal with the heat. How can I get rid of the maggots while still giving the girls the relief of the extra water?! And how worried should I be if they eat them?
