hello! Just after a bit of advice please I have had my chickens for about 18 months. I had a bad rat investation about 4 months ago, I tried everything and eventually bought a treadle feeder and stopped feeding the wild birds and this seemed to do the trick. Anyway yesterday I saw 2 rats by the coop and I am devastated they are back!! I now have a kitten so was considering sprinkling the used wood pellet cat litter around where I have seen the rats, do you think this could be harmful to the chickens? Any other suggestions?! I’m really not keen on poison as I have children and dogs Thank you!
