Disclaimer: I'm not debating or wavering on what I believe chickens should/could eat or weather on not soy or GMO's are angles or devils. Had to get that off my chest 
I have 6 Comets that have been on Green Mountain Organic Soy Free for over a year with great results. It's the only soy-free in my area without going to a mill. Problem is they don't make a soy-free grower or chick starter
I'm assuming it's because they are a fairly new company.
So, I bought Scratch and Peck chicken starter online because I didn't need much for my new 6 chicks and the shipping on a 10lb bag wasn't horrible. In a few weeks I'll need the grower feed but getting anything shipped in 25lb bags is just financial suicide.
My question is, can I use the GM layer feed and supplement to bump up the protein? I can make my own feed but I'm looking for the easiest way. Any ideas will be helpful, thanks!
