Hi there, I have an 8 month old silkie rooster and about 2 weeks ago, he began hiccuping instead of his usual crowing. His energy level began declining and then his bright red comb has become stiff and a darker red. He is eating and drinking very little now. He finds a corner to hide in until I go find him and hold him in my lap. I've given him Vet Rx diluted in water and .5 cc of Tylan 50. Before I do anything more I wanted to ask for better advice. Please help if you can. Thank you so much. I can post a picture of him this evening.
