We had a problem with racoons getting our hens and then a bobcat got 6 in one night. I started trying to come up with a way to keep the chickens safer without spending a fortune, and made my own repellant that has been working for the last six months. We grow a lot of habanero and jalapeno and other hot peppers, so I boil them with cut up onions and chili powder in a massive chili pot. Put it in a huge spray bottle and spray about a foot out from the coop and bingo- no more predators. We even sat out there the first night we put it out and watched a raccoon burn his nose on it and scamper off while desperatly rubbing his nose and sneezing. Was highly amusing! And its cheep since we grow the peppers and onions ourselves. I keep a gallon or so in a big plastic bottle and just reaplly every few days. Anyone else make their own repellant to use around a chicken coop to keep predators away? Interested in other recipies in case they become immune to this one (doubtful, but just to be prepared!).
