I forgot to mention i also give them as much egg layer as they want. Also scratch and some sunflower. They only free range for an hour or so each day while i watch them because i'm afraid the hawk will return.
It's not hot here (on LI) but i do give my 2 girls (i lost 2 more to a raccoon and a hawk!) about 3 cups of green leaves and maybe 8 grapes and a tomato each morning. I gave them some cabbage but they didn't like it much!
