So, I was cleanig out the coop today when I notist all these wierd larvae in the poop. They don't look like maggots which I am really really happy about, but I'm not sure what they are. I have seen a lot of flies in the coop, so could they be fly larvae? They are white and sort of rectangular. Will they hurt my chickens? And, what can I do about them? Please help! I really don't want anything to happen to my girls!
