Quote: x2-- I'm glad to know I'm not the only one tracking down all reasonable animal protein for the chickens.
Quote: In my experience if the hen gets too much calcium, it is deposited on the eggs sheels as tiny spheres in clumps. THey scrape right off usually.
Often fish meal can be used to provide animal protein; only small amts are necessary- like a teaspoonish a day. A complete protein to better round out the vegetable proteins; corn and soy are good combinations to be fairly well matched. add an animal protein and the mix is very good.
( While I"m not a poultry nutritionist I did take a lot of animal nutrition classes. My books would be old and outdated, but the principles are the same. Feed enough good quality proteins and micro/macro nutrients.THe performance of the animal is the best judge.)
Remember that calcium is balanced with other nutrtients to make a shell. THis is where the details excape me-- phorphorus most like ly the other component. ANd specific vitamins to aid int he absorption from the gut into the bloodstream for use. CHickens will steal minerals from their bones if the menu does not contain enough; then during down time like molt replenish the bones.I thought the calcium was the big reason to not feed the layer? The breeder has 3-4% of it. They do get free choice oyster shells so calcium deficiency hopefully isn't going to be an issue.
ETA: what should I be feeding the chicks? I was reading on here that Buckeye breeders were feeding 28%+ protein to their birds they were raising up and getting superior results. Now I was also reading on the Langshan thread that too high of a protein can cause their legs to blow out. Not sure which route to go. High or low protein?
