I'm in Arizona and it's starting to heat up here, which means flies and mosquitoes. We have eight chickens and two ducks, they free range our backyard the whole day and are locked in their coop at night. With all their poop all over the yard or attracts tons and tons of flies. I walked out there this morning and I felt like there was a swarm. We also have a small kiddie pool for our two ducks. I'd like to get a bigger pool or pond but we don't have the money at the time. I will normally dump out the pool and refill every two to three days but I'm worried about mosquitoes, I've already seen a few. It's not a deep pool, it's like two feet deep, lot sure how many gallons or anything. My questions is what are my options for preventing the mosquitoes? I know they'll be attracted to breed there. Do fish work- I'm not sure about putting fish in a small pool like that. Thank you! Any help is appreciated.
