Wait a minute......you had left-over mahi mahi and you gave it to your chickens instead of eating it yourself?!?
No offense, but are you crazy? Food that expensive never goes uneaten at my house. I love my chickens but they're not getting something to eat that runs $10/lb.
Mmm, sounds like the riot this morning when I gave them the three leftover cocktail shrimp (divided into several pieces, in hopes everyone would get at least one). Wow, those disappeared fast! (I think they thought they were giant bugs.)
