Hello,
And my birds like wheat as well, I use it as a higher grade of scratch, milo and cracked corn are not liked so much around my coops. I would not put wheat, or any grain in with the feed, the birds may start to bill the lay feed out, to get to the grain. Use it as a treat, as scratch and just toss your offering on the ground for them to hunt and peck for. Try to limit the amount of scratch offered to your flock, they like it, but it is not as good for them as a complete lay ration.
Best to you and your birds,
RJ
