I hatched 4 jumbo guinea fowl keets in the very beginning of September. I have them living with chicks I hatched around the same time. Two-Three weeks ago the chicks seemed to have cocci so I gave them corid everyday for two weeks and they have been fine since. They are living in my garage currently with the heatlamp and now, out of nowhere, the guinea are acting lethargic. They are drooping to the ground and acting kind of dizzy, it's almost like they can't hold their head up. When they pick their head up, it looks like it's too much work for them and the kinda just bobs around like it's too heavy? I'm not sure how to describe it. They are on chick feed and pretty much fully feathered. I'm not home right now, went out out of town on Sunday, but I'm coming back tonight. This is just my understanding from my parents and the videos they are sending me. They didn't say there was anything wrong with the chicks, only the guinea fowl. Thanks in advanced.
