Newbie here! We just started our first brood and will be purchasing a coop in the next month/6 weeks. We will probably be buying our coop pre-constructed from a local feed store and coop village. They are hand built and lovely coops, we just can't build our own with a one year old running around and taking over our lives! We DO have foxes who we have seen running and playing in our yard. They live in the easement adjoining our yard. (we are urban dwellers). Last year there was a land feud between the foxes and a coyote. We have not seen either of them (the foxes or coyote) yet this year... but I expect to see one or the other soon. I must confess to have fondness for the foxes, but now that we will have a coop of 6-8 chickens, I want to be sure they are as safe as they can be! All of the coops/runs we are looking at are enclosed along the bottom with chicken wire. Will this be enough to keep wily predators out? Should we do any trenching below the coop/run? Also, is it safe to let the chickens roam in the yard when we are out gardening? Truly, I know very little but am learning and reading every day. Tips are much appreciated!!
