Lord, this response got buried. I've had a heck of a busy week, including trying to excavate my big coop of bedding. I may have taken "deep litter" too seriously - I've got about three feet of shavings in there! I think most of it came from that week I had to keep them indoors due to hawk worries, I must've used $100 worth of bedding to keep the place livable.
Anywho, the turkey grow is 22%. I keep most of my birds on all purpose, grower, or turkey feeds pretty much lifelong; I constantly have younger birds and multiple species moving pens, so it makes much more sense for me to feed a high protein feed. My standard pen is on a 20% corn based flock raiser, and my bantam is on the 22% turkey grow. I would actually rather have the bantams on something 18-20% protein but my brand doesn't offer anything wheat-based within that range, and I prefer the wheat based feeds for my little birds. They seem to be a higher quality, last longer, and I like the color better - a nice natural grey/brown. I can't quite afford the wheat for my standard birds, though.
Thanks for the suggestions! How often would you suggest giving the Brewer's yeast and tuna in rice? Daily?
