I am looking to add a couple EE banties to our flock - we have a mix of hens now, one is a buff bantam cochin named Butter - a sweet pretty little girl. However, my son loves the beatiful blue egg our older hen Goldie lays now and then. So the bantam EE is appealing for size reasons as well as egg color. Any opinions on how well they lay and is they are pretty cold hardy? Any pictures or other thoughts? Thanks much!
