I have a narr. tom that has become very lethargic. He has acted this way for about a week now. There are no visible signs of illness or injury. He follows the rest of the turkeys around but he is moving way slower. He keeps his neck down and doesnt strut or gobble now. He usually follows the others and when they start to scratch around an area he lays down. He does still eat and drink, but not with a whole lot of enthusiam. Any ideas what this could be?
