Our 5 mo white leghorn rooster had a horse crow for 3-4 days, now he hasn't crowed for 2 days. He's not mating or eating (very little if any). We thought he may have hurt his voice box with his very loud and often crows. His comb and wattle are very bright red and he did drink a little water this morning. It appeared that he was trying to poop this morning, but very little happened. Could he be constipated? He's our only rooster and I'd hate to lose him. We do not have a poultry vet nearby. Any advise or suggestions would be appreciated. Thanks!
