I just got out of Koi fish due to........wait for it........FLOODING! I had herron and raccons. Dogs and cats. Only lost one fish before I got wise. Solar eletric fencing! Solar you say, can't be so bad... I tried to get the kids to test it and they wouldn't. ( I did raise some smart youngun's) I wound up testing it by accedent and YES IT IS BAD! OOOUUUCCCHHH! Solar fence can go several acres. It won't get the hawks but it will get snakes if you put low eough and keep it clear daily. Its my walk. Racoons, opossums, fox, cats, dogs...etc. get the idea very quickly. Just don't forget to turn it off for you! I'm thinking chickens won't be anymore trouble that fishes, just as satisfying (did love my fishes) and I'll get eggs.
