So, lets see, I know we have squirrels, rabbits, and deer around here. So, foxes, snakes, and other things probably won't be far behind. In fact, we think we heard a hiss of an animal (I wasn't there but the first thing that comes to my mind is a snake) near the run tonight. The birds won't be there for a few more weeks, but what else can I do in converting a chain link dog kennel fence into a chicken run to protect my feathered friends from those who want a free chicken dinner? Considering biting the bullet and buying hardware cloth each week till I have enough. I'm wondering about other repellents as well. I've always heard sulfur works well.
