Hi, my husband and I are in our first year of chickens and are loving it. Our barred rock rooster (10 months old) has been listless for two days, reluctant to leave the coop when given the option to free range, and has diarrhea. His crop feels fine. He lives with five hens and they are fine. We know to put ACV in the drinking water (he is still drinking) and we tried to give him yogurt but he refused it. He usually loves it. We have no idea what is wrong or what to do. Any suggestions are most welcome. We live in NW Montana near Kalispell and are not aware of any avian vets in the area.
