I have 14 chickens, 4 rooster Rockey (Barred Rock), Speckels (Speckled Sussex), Pat (Partridge Cochin), Dave (White Cochin) and 10 hens Buffy (Buffed Orpington), Ruby (Rhode Island Red), Easter (New Hampshire red, we first thought that she was an Easter egger but decided to keep her name!), Lacie (Black Australorp), Aunika (Welsummer), Willow (Easter Egger), Ester (Easter Egger), Blue (Blue Andalusian), Sam (Black Sumatra), and Alice (Cuckoo Maran) NO one has started laying yet do you know why??!!!!!. We hatched our 4 roosters and Sam in Late May and got the rest in late July. They are on a diet of Meal worms, Organic Sunflower Seeds, Organic Whole Oats and Whole Corn (We can't find any organic whole corn) It is winter here but I don't know why they have not layed yet!!!!
