No I don't think our chickens are safe during the day
Our last fox attack was at lunchtime, 7 or 8 killed and strewn around the place, and I saw the fox all puffed out and sunning itself with a full belly in our orchard. Oh if only I'd had my catapult in my back pocket.
That's not the first day time incident here either, sometimes one will pick off one hen a week til they're all gone, or we've had mass kills as well
