I have been intrigued by the appearance, size, temperment, and stories of serama chickens. I would like to get some in the future if I can, but I really don't know much about them and would like to before considering getting them. Is there anything special I need to do when I care for them? I have heard that you need to make sure they stay warm in the winter, but I live in AZ, and it doesn't tend to get much colder than 30 degrees fahrenheit here. Any tips on cold weather, feed, coops, or anything else? Thank you!!
