Thank you everyone. Well, I know we all have our opinions about killing/trapping/etc. But, I know that for us, there are foxes galore, and if its not this one, it would surely be another. I do respect the fox and the circle of life and I am going to do everything possible to keep this fox out. I will call animal control and talk to them about WHY this fox was so not scared of us and about potentially trapping it. We stood there and tried to shoo it away and yell and it, and it just kept on stalking our chicks and staring at us! I wish I had some pots and pans!! This fox does seem to be really active the past 2 weeks or so, so there could be kits and the vixen he is bringing food home to.
I'm looking into electric fencing, but am wondering how fire safe it is? We live outside Boulder, CO and have certainly had our share of wildfires this past year. We have already been evacuated twice since we bought this house last August. I'm also going to get my dad's BB gun and some pots and pans and keep those handy. At least one of those might give him a scare. I will be watching the girls very closely the next few days and will be out there as much as I can. I do work from home, so checking on them, or sitting outside and working for a while works for me!
I'm just still so shaken by today --- it was definitely an odd experience. Let me know if anyone has any other thoughts!
Thank you so much ---
