Thanks! of course i'll keep going. I actually put the feed down and then go out of the coop where they can't see me and observe, in the a.m. i just put it down and stumble back to bed!They won't starve themselves. Persist, don't be so easy to give up on it.
I'm pretty sure they are picking up on your anxiety about the food not working which translates to them as "this food is bad".
I guess i'll be throwing some away until they discover they like it...
