Goodness that is a great price, especially for gamebird feed! Sad it;s vegetarian though. My birds did really well on gamebird feed also- great growth and egg production. I'll try to remember checking the gamebird feed for animal protein the next time. I've kind of been thinking if it does, get one bag and mix it with the layer feed and see how it goes.
Yeah BOSS is not so cheap here either.. the cheapest I could find were 19 for 40 pound bags.
Go with what works for you! I wish I could do the same but oh man too many birds and too many pens..... need something in bulk and dry to mix in with their regular feed.
did you try to grow sunflowers from the seeds? a feed store on my island just brought boss and my chickens love it. I am thinking to plant some seeds near the fence so it will not me disturb at all and I might get some seeds for free.
