So I have had my chickens for a year and they have been laying 9 to 10 eggs a day. I have 11 chickens but I went out of town and had someone else watch them and when I came back they were brooding. So now I only get 1 to 2 eggs a day and that's a big problem because I sell eggs. Is there any thing I can do to promote them to lay and How long do they usually brood for ????
