cabbage water

I have started to pull some of the cabbages from the allotment and where the slugs have had some of the leaves I've gone and shredded them and cooked them up for the chickens. My question is can I use the cabbage water for the chickens as it is full of goodness ?
 
Thanks Mike.

you don't need to cook cabbage for chickens - give it to them raw and then they will get all the nutrients
