2 days ago, when i found the new babies in the coop, i put a small dish in there for them to swim in until i could get to the feed store to sell them. a couple days before that I had put some stall pellets around the big watering tub in the pen, well i went to dump and remove the small baby tub today and when i lifted it up i found A LOT of maggots!?!??. They were not there when i put the tub in either! Do maggots like the broken down pellets? there was definitely no other food source in there besides that and poop. my chickens had obviously been around there, the ground was all 'poked at' and they were all over it after i moved the tub too. this is the first time i have ever found anything liek this in their pen. will eating the maggots hurt my chickens or ducks?
