I am thinking about getting a milking sheep and had some questions about whether a sheep would work out. Here they are my questions: Are sheep social meaning I'd have to get two? Are sheep compatible with chickens (they don't just constantly spread diseases to each other)? Is there such thing as a pygmy sheep? I am gone every weekend in the summer so how often is it entirely necessary to milk sheep? Can I use a picket line? Do I need more than just a 4 by 4 foot shed for winter housing in Michigan? Does a sheep need to be bred every year to produce milk? How much food is necessary every day? All comments would be greatly appreciated! Thanks!!!
