As long as you make oyster shell available for the active layers.. yes, I think you got the idea. Their needs are close enough to one another that most commercial formulations will be within that range.
I have used Purina brand flock raiser (20% protein) for years without issue for ducks, chickens, and right aged turkeys) and it has geese listed to use for all life stages also.. I'm currently using a Dumor product.. All brands have issues at some time and turn over/freshness varies by location. I use Mazuri feeds for my other animals.. mini pigs, guinea pigs.. Brand and marketing doesn't matter beyond personal experience.
Where does this SEASONAL information/suggestion come from and
can you provide links. or corroboration. because despite it being what I previously thought and many folks still claim..the
veterinary sources (I've seen
so far) indicate the opposite is true. When not in breeding season, gamebirds often go on lower protein "maintenance" feed (as one example). There are green tables for individual poultry species on the side of the page as you scroll down in following link from a known and trusted resource (according to me). Though I'm not trying to convince you or anyone else
I still prefer and choose (and recommend) the 20% protein (amino acid) level full time.

It's not easy.. but stick with a formulated ration and keep other things more balanced as a treat or enrichment, and hang in there.. Looks like you're getting it!
Regarding getting needed nutrients from BOSS.. please note this quote taken from the previous (Merck vet manual) link..
"The nutrient requirement values in the accompanying tables are based on
typical rates of intake of birds in a t
hermoneutral environment consuming a diet that contains a specific energy content (eg, 3,200 kcal/kg for broilers).
If a bird consumes a diet that has a higher energy content, it will decrease its feed intake; consequently, that diet must contain a proportionally higher amount of amino acids, vitamins, and minerals"
Protein content is not what makes birds chunky or people.. energy is energy regardless of the source.. How is 4 calories from carbohydrates even fiber different than 4 calories from protein? Though protein content may be directly correlate to muscle development.. that's not chunkiness.. Please note.. I'm TRULY friendly chatting here and interested in your answer.. I'm NOT presuming to know anything!
And yes, molting birds are replacing feathers which despite being only 2% digestible in their raw form ARE made from 90% protein and it's amino acids.. They however are not *usually* laying during this time and that is where the redirected energy comes from and goes to.
Well, I disagree about their guide being suited to environment rather than species.. What good would giving all your customers bad information be and have them end up with sick animals? Also.. how does it defer from the veterinary resource I added??
I do agree about it being a guide and some individuals may not fall in line with the "norm".. and yes of course.. they can't know what
excess feed stuffs you're adding in or account for that. Even the veterinary resource states it's a guide based on "typical dietary energy concentrations".
Sorry, I'm not sure of the whole story.. have you checked for injury?
Diet is a great consideration and you might be onto something! Have you posted video and such, did I miss a link to another thread? Some birds that have been impacted by nutrient deficit *may* not recover from their limping (or torticollis, etc) status even after the correction has been made, especially if persisting for some time already. Is veterinary care or assessment an option?
Hope everyone get's (or keeps) THEIR flock stuff dialed in and they continue (or start) to thrive!
