Thanks for the scientific analysis. It's always easier for me to have facts for a base to assimilate it better, but that's just me. Right now my hens are eating ground orange peels when they won't touch them in the summer....Do they, indeed, know what nutrients they need or is it just they are...
I have mixed the shells directly into the food....kind of a mush, especially liked in the winter for 21 years and never had any troubles of any type I could discern. What is the concern of mixing the dried and pulverized shells into the feed, please?
