Hi, I am new with chickens as I have some white rocks that are only 5.5 weeks old. Sorry I don't know terminology yet but one of the chickens is starving itself now. It will always sleep (standing up?) and not move a whole lot. I never see it eat and it is wasting away as the others are just plumping out. It shakes its head as though the flies are bugging it, which very well could be but it doesn't seem to bother the other birds. It literally is NOT eating. We have isolated it with some pellets and medicated water (tetracycline) figuring it is something bacterial. I have fed it the medicated water through the syringe twice today... each time approx 9 mls. Any advice would be great as it won't last much longer
