I purchased 6 rumpless araucana chicks a little over a week ago, two for sure are cockerels. I would like to keep these two to test breed with (both are gorgeous but have different desirable traits). I plan to section off the very back part of the run for them (10'x 30') and rotate breeding. The total fence height is 6 feet, but I would like to block off the bottom 4 feet so 1.) They can't see the hens of the other two flocks because that will cause them to fight, right? and 2.) So my current cockbird in one of the runs can't see them and vice versa. Does anyone do this and what do you use to block sight? I get extreme cold and moderate snow in my area. I was thinking cheap tarps, but can't find any under 6' in width.
