Anyone got suggestions for a quick growing plant as they seem to enjoy munching the plants so much they don't grow quick enough and was wanting to grow something that grows fast. Was thinking mint as one?

Perpetual spinach (you can plant some now).

A trough or cat litter tray planted with young leaves is a great treat (lettuce is another that grows very quickly) & can be grown successionally for a constant supply.
Great when hens have stripped their runs bare.
Often there's the added bonus of a few extra juicy tidbits in the compost too

any lettuce can be left to run to seed - I sow the sort that you are supposed to pull leaves off as you need them, left alone they will reach about 3 feet high and the hennies love em.

remember too much lettuce though can give them the squits - yuk

Grass.

I find weeds have a funny knack of growing with very little input from me and the girls love to eat them!

As we are coming to the end of the growing season how about popping along to your local green grocer or farm shop and asking if you could have their scraps. Green grocers need to 'dress' things lie cabbage (take off the outer leaves) and often lettuce can go a bit mangy on the outside but be wonderful on the inside. If  they give you rubbery potatoes just boil or bake them, same with other root veg although I've found my girls aren't keen on beetroot. Advocardo skin is apparently poisonous to hens but I give them over ripe ones and they don't touch the skins just completely empty them of the flesh. They will also not eat any citrus fruit. They happily eat cucumber, radishes, sprouts, broccoli, cauliflower etc.

I've found that after I've spread corn on the floor for the birds to eat, the bits which don't get eaten and grow tend to be a nice snack for the chicks - although this works better when the pen split and so half the ground can re-grow. I have read somewhere that you can put some corn seed in a container with a bit of water and leave it to grow, then when it reach's suitable size give it to the birds. I've also been recommeded to grow 'Amaranthus Golden Giant' which chickens are supposed to love. I don't know how quick it grows, but its supposed to be quite easy.

I just let the farmer sow stuff then my chickens help themselves, currently on their daily wandering they are enjoying the local wheat
