I have either a fox or a badger problem, half my chickens were taken in one night. I am going to get a trap tomorrow and try to at least get the badgers (I know they're here) and just maybe a fox, if I get lucky. But I would also like to know what deterrs them, if anything. If I do get the critters that live here, others will replace them - I just want to get rid of the ones that think my chickens are a free buffet, and hopefully keep the new ones from getting too close (yes, I will make changes to my setup as well). Terror-eyes? Ammonia? Wind chimes on the fence (which they pass through to get in)? Any sort of animal urine? I need to deter foxes, bagders and probably martens as well.
