Hot compresses..over and over is my suggestion. I know that can't be easy with a chicken but you need to soften it up. It may take a while. Hopefully someone else will come along and have a better suggestion.
Edited to add: I just read you can put castor oil in eyes...I am heading out to work..but some type of oil would probably soften it up faster...I'm sure you don't have castor oil but it's an anti-inflammatory it says, if you could get some at a health food store, maybe.
