Thank you everyone for the fine info. My birds didn't seem to be doing well on 16%. I mean they were maintaining but not thriving. Then I read that some of these heritage large fowl do better on 22 to 26% feeds. . So I switched them to better levels of protein and they did much better. They did best on Cargill's Agway Meat Bird. Finally put on more weight and their feathers looked great. Technically, historically, the Sussex is a meat bird. The Light Sussex, a variety which was a meat bird bred to lay more eggs than the other varieties. My cocks run with my hens so the higher calcium with the layer feed won't work. Too much for the cocks. I need to keep the calcium to no higher than 1.4. Right now they are doing ok on the S. States Meat Maker. I called Cargill and got Naturewise. Seems their sister product to the Agway Meat Bird the Turkey product. I have never gone as high as 26 or 28 percent with my birds.
The artic blast is finally past after 8 days of very bitter cold. I don't feed my birds corn during egg laying season. I was warned it would make them fat and decrease egg production. Maybe I will try the Calf Manna. Funny, my birds seem to do best with feeds that have molasses in them. Like the Cargill products.
I wonder what that means?
Thanks,
Karen
