Hi all, We live in the Pacific Northwest (near Vancouver, BC), and we are in the midst of building our coop + run. We plan to use 1/2 inch hardware cloth, cover the outdoor run, and generally make it inpenetrable!!! What I'd like to know from those of you in this general area with chickens, is this: what have been your worst pests (ie lice, mites, rats etc) and what have been your most common predators? We also plan to use a metal roof, (it's up already) use adequate ventilation, plexiglas windows (maybe a real one if that's availabalt to us...) Let me know what you deal with!!!
