I have an Australorp hen, about a year and a half old, with a bubble (about the size of a nickel, but slightly less wider than the length of a dime) of liquid in her wattle. I gently poked and felt it to see if I could figure it out on my own, but it appears to contain liquid, and I want to know if it's the start of a cyst or not, and if so, do I drain it (how do I do that?), or do I leave it alone until it possibly hardens and I have to remove it? She also seems to have a dull, very small, off-white speck on her eye, and she's flicking her head every few seconds.
