We have a mobile chicken coop which we move around the yard every 2-3 weeks, with star pickets and a wire fence to give the hens a new run. The coop is permanently open, and the hens are free to go in and out as they wish (we have no predators, so no need to lock them away at night - it is purely for shelter). The hens get quite a large, fresh area every few weeks to free range on. They also have grain - in a feeder hanging in their coop. My problem is that the local pigeons eat more of the grain than the hens do LOL. Is there some way I can stop them - but still give the hens free access to their grain? I have just spent half an hour outside brainstorming. I was wondering if I hung colourful streamers down if that would be enough to keep the (smaller) pigeons away, but not the hens? I'm stumped . . . . and ideas gratefully received!
