Thanks for that Kathy! I know for sure, that the Game Bird breeder formula I had been feeding, has evidently changed their formula, as the chooks now won't touch it! $18.00/50# bag, and they are tossing it aside, when they used to dive into it. The one I use is by Pen Pal, and all I can say is I won't be buying any more, especially at that price! I have gone to a mixture of Chick Grower crumbles (non-medicated), Layer Crumbles, and Scratch. Since I quit the higher Game Bird crumbles, some of my hens are now molting hard, and the roos around here that all had white sickle feathers that were dying, are starting to molt them. Thankfully for the warm weather, most are able to free range, and I do try (when I can afford it!) to supplement with BOSS, oatmeal, brown rice, and other goodies like hard boiled eggs. Me thinks in these days of "more is better", we are over feeding these chooks. I can remember when chickens did what chickens do, on nothing but a handful of scratch a day, and what they got from the yard! Are we really doing our birds justice by supplying vitamins and antibiotics and crazy protein levels?? I have to wonder...Regarding higher protein diets...... This is written by Dr. Richard Miles..... A friend shared this with me, and I think it is worthy of being passed on.
Yes, you can quote me if you wish as the University poultry nutrition professor near you. If anyone calls you can give them my name and I will be glad to talk with them.
In regards to your question about the extra protein you are feeding to your birds by feeding them the Game Bird Breeder (GBB) feed. Your mature birds, roosters and hens, do not require the extra protein that is being furnished to them as they consume the GBB feed. As you probably know the protein is made up of individual building blocks known as amino acids and your birds really have a requirement for certain of these amino acids and not protein per se. The protein is used to only furnish the amino acids into the bird just as the feed ingredients are the furnishing the protein to the diet. So, once the requirement for specific amino acids is met the birds liver will have to dismantle the extra amino acids and dispose of the nitrogen from the amino acids as waste. The waste nitrogen that is being excreted by your birds (and all birds and reptiles) is the white material in their droppings. Whenever the bird’s liver has to dispose of lots of nitrogen from the extra amino acids being furnished from the extra protein in the GBB feed it has to work overtime and in hot weather, as we are having now and for many months to come, this will be a stress on the birds because of the extra heat that is being produced in the body as the nitrogen is excreted. The layer feed will furnish the protein level which is closer to your bird’s requirement for protein and in hot weather this will make your birds more comfortable. Your birds will more than likely do very well and have good condition and performance on the commercial layer feed once you switch to the layer if you decide to do so. Your mature rooster does not need to consume a FRM medicated chick starter. The medication is a coccidiostat and mature birds are somewhat resistant to coccidiosis since they have developed some immunity to the protozoa that causes the coccidiosis. A broiler grower diet (unmedicated and with a lower percent of protein) will do fine for the rooster if you decide to switch. The big Buffs are consuming the oyster shells because they need the calcium for egg shell formation. It is a good idea for you to leave it out “free choice” for them to eat it whenever they need it. Chickens have an appetite for calcium and this means when they need it they will consume it as oyster shells. Again, there is no need for you to mix feed for them. All you have to do is to give them the commercial layer feed and they will do fine since the commercial layer feed has all of the energy and nutrients that the birds require to do well as egg layers. Keep supplementing the greens and anything else from the yard and garden and table and the birds should do well. I hope that this information has been helpful.
One further comment about protein and feathers: I am not surprised that the GBB feed is promoting good feather growth and condition since it is higher in crude protein. When considering the many factors that are required for feather formation, overall nutritional adequacy of the diet is of utmost importance during feather growth and development. Feathers consist almost completely of protein (~90%+) and when the bird is synthesizing new feathers a source of high quality protein in the diet becomes very important. High quality protein contains the amino acids in the proper quantity that will be required for feather synthesis. This is especially true at the time the bird is molting and after which will grow new feathers. However, mature feathers are not living tissue like other tissues in the bird’s body. Feathers are made up of the same type of protein as is found in finger and toe nails, claws, hoofs, horns, hair, beaks, etc. This protein is called keratin and contains a lot of sulfur in special bonds referred to in nutritional chemistry as “di-sulfide” bonds. So, there are two sulfur containing amino acids that are very important during feather formation. These amino acids are methionine and cystine. Cystine is the one that is found mostly in feathers and is made from methionine. So, methionine is really the important one and must be adequate in the diet during feather formation. Feeding the higher protein feed (i.e., GBB), which would provide more of these and other amino acids to the bird, would be very beneficial at the time the bird needs them for lots of new feather formation, however after the feathers are mature the extra protein is of no use for feather formation and is a burden on the bird’s liver as has already been discussed. If a feather is lost now and then from the bird, as we know happens at times in the barnyard, it should be able to grow back with no problem as long as the diet the bird is eating is of high quality.
