We are planning on getting either a cow or a goat for milk, but need to know which is better for us.The following information will help. 1. We have 5 acres 2. approximately 1/3 of that is woods 3. We have a five year old and a two year old and if one of those animals might hurt them we need to know. 4. We will be getting pigs, so if that will affect anything i would also like to know. Thanks!
