I recently bought some pigeon spikes from you, not that I have a pigeon problem, but I have a chicken problem! My current small flock of chickens had decided that they didn’t want to go into their coop at night and preferred to roost on the top of the coop. As I have a very expensive automatic door on it this was starting to annoy me, having to go down at around 10pm to shoo them in. Then I thought of your spikes and now no more roosting on the top of the coop and all are going in to roost properly. Result!!
