This is our 4th flock and I haven't seen anything like this before. Does anyone have an idea what it is? It feels like fluid, like a water balloon. This chick is about 10 days old, and hasn't been doing well since Wednesday or Thursday. I have been feeding with an eye dropper. She will sometimes drink from the waterer if I put her beak in, but not all the time. She is weak, and just lays down much of the time. Any thoughts?
