The only place really close to me sells something called K (for Kruse I think) 17% Lay mash by Western Milling LLC (Goshen, CA). The girls eat it just fine, but I keep hearing about different brands and have to wonder. Also, they started out on chick starter, and now at 21 weeks are on this Kruse mash. Are there better brands out there? Does it matter? Also, what exactly is the difference between mash, crumbles, and pellet? I can guess, but from some of the posts I've read, I might be wrong. I would REALLY appreciate some help here. Thanks. PS: I sincerely apologize if this information is located elsewhere in the forum and this creates redundant answers....I did search and read whatever sounded helpful but not all questions were answered.
