First of all, I've seen two opinions regarding roofing: 1. Give them a low roof so they can't jump. 2. Give them a soft roof so they don't get injured. Which would you say is better, or would you suggest something else? Also, I'm wondering about the coop is made of/from in general. I'm new to quail so any info is appreciated EDIT: Another question. How separate do you have to keep them from chickens?
