I was debating using hardware cloth halfway up and chicken wire on the top portion of a walk in run. This would serve two purposes. One, I'd be able to see into the walk in run better for chicken viewing from the porch. Two, it would save money on putting it all the way up as it's a six foot high run. 1. Any issues with doing it this way? 2. Girls would be locked in the coops most nights but if we were ever late home they could be out later. 3. Thinking of plastic lattice for the roof with possible hardware cloth underneath it. No predators to speak of so far (four months) and we have a six foot high, solid cedar fence outside the run.
