I stopped using
TSC feed (Dumor, I won't buy it anymore) after some bad results-hens stopped laying for 4 months when they molted, and I got some bags of scratch feed that were full of hulls and bug poop. The hens did not resume laying until I switched to the source and feed below:
I found a small, local, family owned feed business that carries feed from a local grain mill. I gradually switched over to layer mash, and when I want to increase the protein I add distiller's grain. (25% protein) They've done much better on this. Even during molt, they don't stop laying altogether like they did before. they slow way down, but I alway get at least enough eggs for our own use during molt, and the rest of the time I have plenty extra to sell. They also get through molt faster. My chicks are healthier, too.
I feed whole corn and black oil sunflower seed as a treat, instead of scratch grain.
Why people add water to mash I don't know. They do fine with it dry. Some seem to think it needs to be cooked. It doesn't.
You might ask your mill if they also carry distiller's grain. My birds really like it mixed with the mash.
