I want a spray to stop my chickens from pooping on the porch.

Contrary to popular belief, chickens actually can be house trained, or porch trained. A friend had a chicken that would fly off your shoulder, run out in the yard and do his business, then run back up to you wanting to be picked back up. Even so, if you don't have hours & hours to spend with each of your chickens you will just need to keep them off the porch, there's no magic spray to keep them from pooping there.

personal experience

sorry the only way to stop your chickens from pooping on the porch is to fence them off the porch. Chickens poop everywhere, even in their food. If you don't want the chicken poop there then you can not let the chickens in the area.

im afraid theres no spray for chickens to stop them pooping off the porch
