I've been searching the threads for some answers but figured I would just ask. I have 5 girls, 1 Red Rock, 1 Light Brahma, 1 Gold Wyandotte, 1 Jersey Gold and my little mille fleur d'uccle bantam. All of them were purchased at 4 weeks old and get along beautifully. Ironically my Brahma is the boss and her favorite sister in the Bantam. I am not worried about the bigger birds for the winter but am a little concerned about my mille. Can anyone share some insight on the situation. Will the bigger birds provide enough warmth for her? and am I just being an over protective worry wort?
