Hey BYC, I'm building my first coup and run, and my 6 chicks will be here in a few months. I have a very limited budget, but a lot of resources and questions. I plan on building my coop with a wooden shipping crate and modeling my run and design based on geek2nurses coop. https://www.backyardchickens.com/a/geek2nurses-diy-coop-run I plan on making my run out of a fully enclosed rectangle of cattle panels. I also plan on making a autofeeder and waterer out of chicken nipples and old 5 gallon buckets. Here are my questions: 1) Will I need to reinforce the cattle panels with chicken wire to keep predators out? 2) Can I leave the coop door open if the run is completely secure? Any suggestions are greatly appreciated, thanks!
