I would say above 4'.That's good to know. We're still not sure how many Tom's and Jennies we have... 4 and 4 maybe, or if we're lucky 3 and 5.
I do have a question for you - in another thread you mentioned the dangers of chicken wire and turkeys... Do you think there is a safe height where I can switch from hardware cloth to chicken wire? Above 3 feet? Above 4 feet? We don't want to risk our Tom's.
Personally I don't use hardware cloth. I am using 2"x4" welded wire. Unfortunately poults can walk right through it.
Hardware cloth is better.
