I will not kill the animals. I will not let my dogs chase them. I will not spend money to contain chicken boy's chickens. Please help
If you can catch the chickens, you could might be able to hand them over to animal control as "stray animals."
(If you want to catch the chickens, you might be able to use a fenced area or dog kennel like a large live trap: chickens go in, you close it up, then you can go in and grab the chickens.)
