Could it be that your pullets are thinking “you know this guy is dumb if he thinks a Whopper is real food”?
Well, I dunno. The older chickens will literally attack me for such a treat. (It’s almost like the “Compies” scene in Jurassic Park II, only if the hens are out free-ranging, it happens quicker!) And, that’s what a Whopper is to me, now. If I’m having one of those “need 40 hours in this day” (and probably traveling) days, a Whopper once a month is a nice treat. And nutritionally, it’s actually a heck of a lot better than most fast food. I’m no food snob, but, I do try to moderately limit my overall sodium, calories, etc. (It seems to be working - I’m the same weight I was 10 years ago - maybe should lose 5 lbs., but am fairly active & certainly nowhere near obese.)
Now, if you want to insult someone for eating poorly, I’ll introduce you to my Mom’s part time sitters... (Eye roll)
