Just wondering if anybody ever raises fish for their chickens. What type of fish would be most efficient and reproduce quickly? I was thinking about guppies or small goldfish, maybe those mosquito eaters. I have rain barrels so they could stay in them. I can add a few bubblers. Here in AZ, the summer heat would require a tropical fish ( guppies?mollies? ) for the summer but in the winter I'd probably want to switch to a cooler water fish, probably goldfish, since they're readily available and cheap. I was also thinking about putting duckweed or watercress onto of the water for both the fish and the chickens, since it grows so well. Just a thought. I used to always have goldfish in my huge water troughs when I had a large farm and they thrived. I used run-off water from gutters to keep the troughs full and rarely needed to water the thirty head of cattle. I never did try catching the fish for the chickens. Don't remember getting over run by goldfish but I didn't provide any hiding areas for the babies so they were probably eaten b the adults. The koi in the koi ponds did reproduce a lot.
