Hey there, I'm new to the site and am one of those paranoid people that want to get everything right and have lots of questions, so sorry in advance... I've heard that chicken wire isn't as protective as some think, so I'm building mine with wielded wire that is 20 gauge wire. The grid is 2"x3" and I was wondering if that is to big? I have had problems with raccoons eating my cats food in the past and I'm worried about them getting the chickens and their food. I was wondering if someone had any knowledge of how long their arms are and how far away from the sides I need to put the food. Also, if I put the run on 16" cement stepping stones do you think they would be to dig under they coop? One more thing, if the whole coop is in the wielded wire, do I need to close up the coop for the night? I'm in San Jose, Ca and it only gets down to the 30's a few days a year so I wasn't to worried about the cold, should I? Thanks for any help.
