Now, see..that's where we just have a difference in husbandry methods. I actually reduce total proteins in the winter because they will slow down as a part of their natural cycle. If I kept high production breeds it might be different and maybe that is what you are doing, trying to keep up with production layers during cold winter months. I've never had to do that because I keep dual purpose breeds that naturally slow down in the winter, so I adjust their nutritional needs accordingly.
I cut total proteins at that time and add a little fats...much like a wild bird would transition to. I always manage to have eggs in the winter, though not at peak production which is as it should be..winter is a definite slow down time and I've experimented with supplementing proteins and fats during that time and not supplementing, and I saw no difference whatsoever in the production levels of the birds. So, I chose to not only
not supplement, but actually drop total proteins...both for economic reasons and for the simple fact that they do not need added proteins to keep warm or produce at the level they are producing. It has turned out to be beneficial to their health and their longevity over the years.
I cut a 16% layer rations with about 6-9% whole grain and add some BOSS but not overly much. It has the fat content I want without increasing the proteins I do not want. That's about as fancy as I get with feed mixes....no need to mix complicated feed mixes if you use a layer ration as the basis of your feed mix. It over complicates life and it doesn't yield anything different for the chicken except maybe to shorten their laying~ and actual~ lives when we play with unnaturally increasing their dietary intake of proteins and then forcing them to eat it as it's the only game in town.

The starter I get is 18% and mix it with layer now, so my chicks don't even get the benefit of that 18%. My granny used to feed chicks cornmeal...that's it. They were out on range so fast that they got natural proteins for their needs,as are mine.
I have no understanding about this growing birds require more protein content...no more than you'd increase total proteins on your toddlers beyond what their 12 yr old brother may be eating. Babies? Yeah, they get higher proteins as they nurse but a chick is no longer a baby after it has fledged and is then into the toddler stage, IMO.
No matter if you ferment your feeds or not, high proteins are not required to raise chickens at all...I seriously don't know where people are getting this information!
Commercial ag poultry may increase proteins for broiler birds on a grower mix but they are living fast and hard and it often results in them not even making it. Layer ration is mixed for production layers at 16% and no more than 18% and that's commercial layers...why in the world would a backyard hen need more proteins than a commercial laying bird that lays steadily for two years, day in and day out until they burn out and
also do not live long? Is that the goal for a backyard flock? If so, I missed the boat..I actually want to keep my birds around a bit and I also want them to live a healthy life while they are here.
Just like one would not feed the family pet a high pro dog feed for sporting and hunting dogs, and wouldn't feed the family horse high pro feeds one would feed a race horse or a work horse, one shouldn't feed a hen that walks in a coop and run all day, lays 5-7 eggs a week during peak laying season and has seasonal slow downs high pro feeds either. They will get their kidneys burnt OUT, their cardio system will suffer, their liver will be fatty and they may develop bumblefoot from gout, general illness from a weakened immune system as their organs go into failure, laying issues from the fat around their reproductive organs, respiratory issues as their abdomens fill up with ascitic fluids...the list goes on.
I'm getting reports from several points this year of just this type of problems~resulting in sudden death of young birds, I might add~ in people's flocks and this is the first year I've heard of it being this bad...for some reason, folks have gotten on this kick of mixing their own feeds or feeding wild game bird feeds or wild bird feeds to their flocks so that they can avoid feeding so much GMO.
Seriously??? Do they eat ketchup, jam, syrup, spaghetti sauce...well..the list is ginormous of the things that have HFCS in them that people eat every day and they are going to worry about GMO seeds in their chicken feed? Feed the kids high fructose corn syrups, but by golly, don't you feed the chickens that stuff! It will get in our eggs!!!
That is called gagging on a gnat and swallowing a camel, in Biblical terms.
Sorry...this subject just burns my bippy and I am not directing it at you, Michelle82, but when the question arises, I must take this opportunity to get that bag of snakes all laid out in a row...please don't think I am trying to insult you with this, because that is not the intention.

So, to answer this question....why is anyone feeding that high of protein to a chick in the first place? I know this is a hard thing because you just want to do what is best for your chicks and chickens, but more does not mean better when discussing crude proteins fed to chickens.
I got into fermented feeds not to increase the proteins in the feeds I was feeding, but to make them more digestible so that they are actually
getting the proteins in the feed in such a way as to use it appropriately. I think when people saw how well that was accomplished they made that age old mistake and said, "If some is better, more must be best!"(I do the same thing when dealing with detergents, dishes and laundry..
) and started increasing the proteins in their feeds to get the "best" nutrition. Since when is a high protein diet for any animal that isn't being fattened for market the best of nutrition...even us humans?
The fermentation of the feeds does
not increase the protein percentage of the feed, it actually changes the type of protein to a more perfect protein that can be utilized by the bird at a cellular level,thus increasing the absorption of the proteins by changing them to amino acids that can be used by the body. Ruminants do it all on their own and even horses and rabbits have specialized bowels to do this,but chickens and pigs do not, so this just helps them digest a grain based diet that they wouldn't normally be on in the first place if they were fetching their own diets out on forage.
So, yes, fermenting high pro feeds will make that level of protein fed more bioavailable but a chicken can only metabolize so much of that before their systems suffer under the strain of too much of one nutrient.
