Well, not exactly the same.. but should be *similar* in nutrients (within a range regarding specifically protein (17-20% ish) and calcium (1-2%)).. with regards to chickens. Some starter/grower may be deficient in niacin for ducklings, or amino acids etc as compared to "flock raiser", if not being used for chicks or chickens.. ie, turkey, game birds, etc. Just for basic full disclosure purposes.Is flock raiser the same as starter/grower? I buy my feed at tractor supply and I only buy organic. It looks like I only have a choice of starter/grower and layer.
I'm quite impressed to see how many offerings are available and continually changing at TSC! Check out their site often to see what formulations they might have available and which one you like the best. The even offer free store delivery on some items that aren't carried in stock. And I get my guinea pig food delivered to my door free when spending $49+, So I add an extra bag and spread out my deliveries just a little longer.. yes, I bought 75# of QUALITY guinea pig food for $60, that's a steal! Sorry for the cheap shot sticking in a photo of 3 of my little stinkers, the Three Amigos.. Honcho, Poncho, Sancho.. in that order. I have 7 boars and 2 princesses!

But you are correct it is challenging to find a "flock raiser" that is made or certified organic.. And those are usually easiest found in starter or layer formulas. I try not to be anti-layer.. but holistically (IMO) speaking for the bird and even your family the starter/grower, with oyster shell free choice on the side is a better long term choice than layer. Egg shells are fine but not usually enough to sustain a layer long term. The only thing layer has that others don't is the added calcium and usually decreased other nutrients (protein is the main one), but still consider acceptable as meeting their need at or above a prescribed minimum according to the species and age it is labeled for according to law in the US.
I agree with most of what the other poster said except the protein causing angel wing.. which according to my research is more genetics coupled with excess energy from ANY source. The lack of niacin cause them leg issues not angel wing either. Still, fairly informative and obviously some effort put into the post!
