Growing plants for chicken food

Hi all,
I would like to start growing some plants especially to feed to my chooks during the winter.

During the summer they freely roam on the grass in my back garden and eat enough just to keep me from having to mow it. However in the winter months while the grass isn't actively growing, they have eaten it all, and are now almost down to bare roots (which I hope will start sprouting soon!). I'd like to supplement their greens by growing plants I can feed them to save the 'lawn'.

I have a medium sized front garden which needs a complete renovation, and had a sudden thought - could I use it to grow chookie dinner?

Some thoughts on ideal candidates....

- Plants which are 'cut-and-come-again, or bushes I can trim would be better ; only original set-up required or minimal maintenance, as I won't have a lot of free time to tend it.

- Things which (obviously) chickens like to eat

- Plants which are not particularly obvious as a vegetable plot. A front garden full of cabbages and tomatoes will get me some funny looks from the neighbours, and I'll likely have anything too yummy-looking going AWOL.

- Plants which will be green during the winter, as that is when they'll be required.

I've no idea if this is an impossible request or not, but I thought I'd ask and see what you could suggest!

Thanks,
TT

Yes you can 'Give peas and chance' it was good enough for John Lennon, but you can give em sweet corn if the Jolly green giant dont catch you 

not sure whether hens like campanulas but they are good salad plants and attractive for a front garden

put a whole cabbage in, mine prefer spring cabbage (grow all year) and I have spinach and chard in the polytunnel. Most veg will not "grow" over winter unless you can get it undercover and then slowly.
Look for small polytunnel (poundland/wilkinsons etc) and use a couple of them for growing round lettuce and perpetual spinach and grab leaves from each.
