I'm afraid I don't know the answer to the chicken question, but here's a use for all the green bits !

If you pop them into water they'll keep til December, then all you need to do is get some green florists wreaths, soak them in water and put in the wee green bits, cover the ring making it full and bushy (but leave a clear space in the middle) decorate with some sprigs of holly, pine cones and ribbon (dried fruit looks good too) et voila - Christmas wreaths, punt them at £10 a time and you'll have people queing up to buy them

Sorry, I know this doesn't answer your question - but it's a shame not to make use of what you have I always think.
