First year wintering chickens. They are warm, fed, and watered daily. We have 13. Bantams. Mixture. However we have 2 guinea hens and one of them seems to be keeping the rest away from food and water. Even the 3 roosters. They are all huddled up under our bunny cage and won't come out. I have noticed water consumption slowing down greatly and can tell some are losing weight. Some are still laying. I have lost two this past week. Should I remove the guinea?
