I have an almost 3 wk old light brahma chick that acts drunk! No obvious injuries. She just can't walk. When she tries, she flops over, flails about, etc. She didn't act this way initially, I first noticed it about 4 days ago. I began treating her with Sulmet solution as the most obvious answer via Google was Coccidiosis. No other bird in my flock of 15 is showing any signs of problems. We've been treating her for 3 days now with little to no sign of improvement. We've isolated her, hand fed her food/water, kept her warm...but still not getting any better! At this point we're ready to put her down. Is there something else I'm missing?
