The relatively cheap,16% protein, chicken layer that I use switched from using roasted soybean meal as the protein source, to urea as the protein source and the number of quail eggs I am getting dropped by 90%. The actual ingredients do matter, not just the total nutritional levels contained.

What????
The only thing that can use urea for a protein substitute is cattle. I would be asking some serious questions most likely through a state agriculture inspector. The feed has to meet the specs on the tag and I don't see how it can with urea in it.
