depending on what turn over you want really what breed would you want if you want good tasting sheep then go for a certain breed but then if you go for a primitive breed it will take longer for the lamb to mature. are all the fields well fenced as you dont want pigs sheep mixing as they will kill them. then with cows what handling equipment you got for them whats the tb testing like in the area? how many you hoping to have of all these animals and what sort of rotation will you be running? as piggs will churn up everything you have rooting if there not confined so that limits what you have other livestock on such small acreage hope this helps
