Hi, we live in a residential area. Our backyard is approx 50 x 100 ft. We went to our city and got permits to have 3 chickens and 2 goats. Now I am wondering if the goats would do ok in our size yard. I would get a kennel for them and also a house to sleep in. I was thinking of a kennel enclosure of either a 15 x 20 or 20 x 20. They would be in it only when no one is home to keep an eye on them. We do have the occasional raccoons and opposums that come into our yard. Are they a danger to goats? Which is better a pair of wether pygmies or Nigerian dwarf goats. Thank you for any help you can give me before we embark on this endeavor. We do not have any dogs or cats. Just finches and now 3 chicks.
