Glad to report tonight, that Clyde has pulled through! This afternoon was the first time I've heard him crow since last Friday! He was also fence fighting with Pip who was standing by the gate. Never thought that would make me happy, but it did!! Just a note to all who may use Eprinex, only put one or two drops on the neck!! It dawned on me that all of the hens, and two other roos had the drops given under the wings or on the back. Clyde was the first one I did, and when a hen spooked off the roost, he flinched, and the whole lot I had in the eye dropper went onto the back of his neck. Granted, it was probably 7 drops, but that is TOO MUCH! Especially loaded in one place. While he did not act sick, he was indeed droopy, and like I said, didn't crow. Whether the B Complex helped or not, I don't know, but it did make him eat and drink more almost instantaneously. Just posting to share my joy, and to pass on what I almost had to learn the hard way. Hope this helps someone else avoid my mistake!!
