Hello, we have been thinking about getting chickens for a while now and are moving that way next Spring. Found this site and looking forward to learning more. Thinking we are going to get banthams (the smaller chickens) but want to find ones that lay good/healthy eggs. A little worried about our 2 dogs but think they will get used to the chickens after while. For 2 adults and 2 kids, is 2 chickens enough, or should we go for 3?
