HWC seems possessed sometimes too- especially if you have taken off a glove for a moment, it attacks-lol.
We are trying to source fencing to complete the run fence. Currently we have chain link that is short at 4’. But it is hard to find fencing. We’ve been able to roof our run over the past 3 years. With the short fence chickens can get out. So we put up fine deer netting, secured with long pieces of wood to the roof posts. It works well, but is not perfect. Bc it is fine/thin, it can get broken, but having the long strips of wood helps keep it up. So, adding something like deer netting can be a possible option if something is needed quickly to keep out small birds. When we have chicks in the run, they can get out of the chain links. So, we use a stiffer green plastic garden fencing with small diamond openings zip tied to the chain link to cover the large chain link openings. The zip ties break down over time, but we only need the green fencing up for part of the year.
