I have a rooster, Nugget. He's a Rhode Island Red and a beloved pet. He and his two girls get locked up at night, but during the day roam the backyard (1 1/2 acres) with the pygmy goats. He's not quite 1 1/2 years old. He likes hanging out in the pygmy goat pen looking for spilled oats, etc. He gets held and petted and treated pretty much like a big baby. A couple of weeks ago, my daughter was holding him and became alarmed because he was breathing hard. When she tried to set him down, he didn't seem to be able to stand by himself, and his crop turned very dark. She held him in her arms for about 15 minutes and his breathing returned to normal and his crop color returned. The next day I noticed he had diarrhea, so I gave him a couple drops of imodium with an eyedropper and that seemed to clear up. We also added extra grit to his diet in case that was part of the problem. Since then, he's had a couple more of these breathing attacks that we've noticed. None as severe as the first one, but troublesome nonetheless. He also seems more complacent than normal. He doesn't try to get away when turned upside down and cradled in the arms like a baby, and he doesn't follow the chickens around as much as before. He's content to stay in pretty much the same area all day. The chickens don't seem to be having any problem. We're new at this. Does anyone out there have any idea what his problem could be?
