I have eight standard size hens (NH Reds, Black Copper Marans, Australorps, etc.). A friend is giving me a few "Sizzles" . I've never seen these before. Are they always bantam sized? Do they do well in a mixed flock, or do other hens tend to pick on them because of their unique feathers? If so, I will re-home. Would like a really cute, sweet hen or two for the grand-kids to enjoy, but want something that lays decently also. Thanks for any advice from those with more experience!
