About 3 weeks ago we treated our young flock for cocci, (5 days). One ameraucana was sluggish and anything we tried didn’t help, so we tried Corid. All seemed good after that. Today our silkie is just sluggish and sleeping. This morning would not eat or drink. Gave some nutridrench and separated from flock (don’t want her getting pushed around). Seems now there is a smidge in her crop now. Should we treat with corid again?? Only thing other than sleepiness is a few sneezes. Photo of our girl in question
