OK. I guess I won't sweat the 2-3% then. I'm considering fermenting just as a way to combat the infamous meatie stench. And since I've done some reading in the FF thread, it seems that maybe it makes the nutrients more available to the birds and that would help things as well. Dunno! Will...
70 birds. I wouldn't be opposed to buying some sort of supplement like fish meal and mixing it in myself, I'd just need help with how much per 50# bag.
Is there something I can amend my 20% broiler feed with to boost the protein a little bit? Or, is the impact of the extra 3% the hatchery recommends not a big impact? I found a local source for non-gmo feed but they don't carry anything over 20%. Help?
