Fermented Grain and A Swimming Pool

This post could also have been titled, the experiment that didn't quite work.
But let's start at the beginning.

Friend, Kris, texted to say a brand new local brewery was disposing of spent grain that could be used for chicken feed and for pigs and goats.  What a find!  Free donkey and chicken food.

I did do a bit of checking online to see if the stuff was safe and found some farm folks have fermented their grain intentionally as they believe it's more nutritious.  OK, we're good to go.

So Rick scooted over and we received a 25-lb barrel of fermented grain.

He immediately scooped a generous portion for the donks.  They walked away.  And would not return to the bowls.  Nope.  It was icky.

So then we tried the birds.

And they agreed it wasn't bad, but they didn't consume enough to make a dent.
Soooo, a quick text to the neighbor to see if she wanted 25 lbs of grain for her cows and we were able to pass it along.

It was such a good idea...

On another topic --

I find there's always a bit of jockeying around to make the donkey and chicken environments as pleasant and healthy as is possible.  To that end, the wading pool that had been in the chicken run for their amusement (but was also a failed experiment) was shifted to the donkey yard to allow for easy feeding without the consumption of dirt -- NOT a beneficial extra ingredient.

Yes, standing in the pool is always helpful.

And the girls got the two tires that the donkeys have ignored, and, a branch.  I'm not sure the tires are a hit (just something to climb on) but the branch is getting a little more attention.

I wish I could hit on a toy for the donks that tickled their fancy but so far everything has been a flop.  Fancy Jolly Ball - no.  Beach ball to toss around - no.  Tires to nose around - no.  If anyone has a suggestion, I'm all ears, as are the donks.
