Oh hey, I forget to tell you that we get our feed tested at Parkland Laboratories in Red Deer. Probably a bit easier for you to get to than Saskatchewan. They test moisture, protein and all the macronutrients plus sodium for us, and they'd probably do more if you were interested.
To all you barley folks, I don't like feeding too much barley or oats because of the hulls and I think birds with their short digestive systems benefit best from nutrient dense foods. Unless you get dehulled, in which case barley and oats have fantastic feed value.
Also, lazyfarmer; does your dad rot the wheat on purpose?
Finally, KathyS I understand your desire to both make your own feeds and determine the potential for size in your birds. Animal proteins are always best if you can add them. All commercial rations have to add amino acids, especially methionine, which are particularly in short supply in legumes but are abundant in animal protein, especially fish. In the summer I don't worry because the birds are getting lots of animal protein on their own. In the winter, I add the sunflowers to at least try to balance the methionine a bit.
I have similar desires to you in the feed my own but still get big birds department. One thing of note is that in Genetics of the Fowl, Heuser states that some research done back in the day showed that birds fed poorer diets early, even though they had less growth in the first couple of months, tended to compensate for that growth again later in life. I also know that some turkey producers now intentionally decrease the quality of their feeds to encourage more skeletal growth early on because they know the birds will just compensate for size later anyway. It increases the market value of their birds at butcher time. This is useless information for a cornish rock or whatnot producer, because they expect to butcher their birds far to young to get any benefit from compensatory growth, but it is incredibly valuable for us heritage breeders. Starter and grower were designed for commercial broilers, not for our birds. Lazyfarmers dad has the right idea (except for the mold part maybe
)
I am currently on a thought to breed for birds that specifically do well only on feeds that I or a neighbour can grow, kind of a hundred mile chicken diet.
