Luckily our chickens have not been attacked, but thats because they stay cooped at night. The bunnies were roaming free in the run, but not anymore.

I tried some jungle chickens that roost in trees like Guinea fowl. They do much better at surviving, but finding the places they lay their eggs is like having an Easter Day hunt every day! I have no solution for the poor rabbits, their evolved coping tactic is prolific procreation!
Its hard, but its part of life i guess.
