I have 4 hens and a rooster living in my rabbit barn, they came in here when a weasel killed all their mates in the chicken coop. We fixed the coop and it is now tight and safe, but they will not go back. I accepted defeat and put in a roosting ladder and some nest boxes up high. Things were great for awhile but then a raccoon attacked them on their roost and killed a hen and the rooster decided that the roost is no longer safe and moved them to a spot on top of my rabbit cages. I have placed plastic and metal sheets to protect from poo getting on the rabbit but to no avail! Chicken poo is always ending up in the cages and I have to hose everything off daily. With cold weather coming I want to get them back on the roosts! I have since caught the raccoon so that is no longer and issue. I ordered some plastic bird spikes to try but they are pricey.
