7 Heritage breed poults that I've had since they were 2 days old; 5 Bourbon Reds; 1 Standard Bronze and 1 Narragansett. They just turned 8 weeks old today and it looks like I might have at least 2 Jakes (the other 5 I'm on the fence as far as sexing). The Narragansett is definitely a Jake and one of the BRs is looking very Jake-like. Anyway, I digress. Reading thru all the feeding threads, I'm so confused as to what to feed them next and at what age I should switch them over to a grower feed. They've been on Game Bird starter (30% crumble) since I've had them and they've done quite well; they've not had their feet on the ground yet. I'm trying to hold off until they're around 12 weeks old before I allow them to venture outside, though the timing might change since they're growing like weeds! I'd like to start mixing in a grower feed with what I have left of the starter, however, here's where the confusion sets in. I've read threads where some folks switch to a 20%, 21% or 24% grower feed. I'd like to keep these poults on a healthy path; I'm not raising them for meat. So, what's the next best step? 20%, 21% or 24% grower? I can get a 20% turkey grower feed (small pellets) locally, however, is that enough protein at this age? Should I be adding anything to raise the protein level? There are so many feed choices for chickens, but just not that many options for turkeys. Thanks.
