I've used the wheat in the past, both when I fed dry and with the FF...both times the birds always left it to the last and sometimes they wouldn't eat it at all. That's the only grain I've ever given my birds that they didn't want to eat. I'm assuming it was due to the extremely hardened hulls...they won't even soften in the mix after having been in there for weeks. The meaties wouldn't even eat them and they will eat the shoe strings right off yer shoes!
I'm sure wheat is ground into the layer at some point.
This is so good to know. I'm thinking of supplementing or mixing my own feed mixture and was planning on using wheat as the bulk ingredient. I'll give it a try first with a small batch to make sure our birds will eat it!
