A bobcat got most of our chickens last year, the one that's left is living with a flock down the street. We're considering Jersey Giants next, and adding a rooster this time. The pen is our garden, 50'X50'. The fence is rabbit fence topped by barbed wire, about 4.5' high. The plan was to run the chickens in half and garden the other half and then switch. Now we're thinking about letting the chhickens run in the whole garden and just fence off the veggies. Any other suggestions?
