Avidin and biotin. Whole cooked/uncooked chicken eggs - a problem? What's the story here relating to the uncooked egg whites fed to ferrets? Is there a unique and strong binding of avidin to biotin internal of the ferret? What are symptoms of biotin absence in ferret's system? How to quickly replenish low level of biotin before ferret dies? Does low biotin affect available food residue 1/670 part or less in ferret poop? What is formula that yields surface area A of ferret food particle halved n times? What is surface area of a sealed ream of printing paper? And upon opening and separating 500 individual sheets of paper, how much has the surface area of the paper increased? Contributions to the questions much appreciated.
