I want to get some cornish X. I have seem the tractors for them, which I love the look of. My question is, do you keep them there at night? I have racoons and the occasional fox. We trap what we can, but you know how it is. Too smart, too big. Do the tractors keep them safe at night? It looks like just chicken wire on most. I have a chicken coop, but the top is open in the run, and they jump down to the run. I can build a ramp, but my chickens have made it bare earth. Just wondering if there were people in my shoes,and what they did. Thank you.
