Yesterday I went to a local farm (the lady I get my eating eggs from, actually) and bought eight 3-4 week old ameraucana chicks. They all looked healthy and bright eyed. I brought them home and let them run around in a small "play yard" outside and let them meet my nine 2 week old keets, who are going to be their brood mates for the next few weeks. They got along famously, and when I went to bed last night they all, keets and chicks, seemed happy, active, and healthy. This morning one chick seemed a little more tired than others, but perked up whenever I touched it or moved around. Now, though, the poor thing is so tired she can barely lift her head or right herself when she tilts over while sleeping. I immediately got some corid and dosed the water and feed, even though her poop looks solid and non-bloody. I also have some poultry electrolytes and pro-biotics, but haven't given them because I was afraid it would not do well with the medicine. I don't know what to do...I really don't want to lose this one, not less than two days after getting her. I hate the idea that I might have bought a healthy chicken and then accidentally killed it. Please, any advice?
