Can you feed sheep flint corn?

Hello, my family has a small flock of Shetland/Finn ewes with a BFL ram. The resulting lambs being F1 mules. This is the first year with the BFL ram. Normally the Shetlands we butcher are VERY lean and small due to genetics and being strictly pastured, no grain. I wanted to fatten them with corn that I grew myself. I know sheep can eat field corn, but can they eat Indian flint corn? I grew a lot last year to use as flour, and I wanted to plant a quarter acre of it to fatten up some sheep we’ll be eating. Thanks!

If they'll eat it which I'm sure they will.
Just be sure to introduce it gradually.
You don't want one of them getting too much of a good thing before its gut has adapted and it ends up with acidosis.

If I'm not mistaken, sheep are susceptible to urinary calculi, as goats and even pigs are.  Females tend to do okay on grain as they can pass stones more easily.  But a single wanton venture into the grain bin by a goat wether can kill him, as the grain can create calcium stones that can clog the urinary tract if they're too big.  It isn't a guarantee.  But it can happen.  It almost happened to my goats; a gate got left open and I found them head-first in the grain bin (which was primarily corn).  They had painful, blood-tinged urination for like 2 weeks, I was holding my breath.

There are minerals on the market that have... oh what is it... ammonia chloride...?  Do not quote me on that!  It's ammonia  -something-.  It's in some commercial minerals, and that chemical is supposed to help break down calcium stones and help ward against UC complications.  MannaPro adds it to their loose goat minerals.  But if my memory serves me, because that compound is in the mineral, you have to ration the minerals, they can't be fed free-choice, as per instructions on the bag itself.  
I prefer to  buy higher quality minerals that are safe to free-feed, and I just don't grain my ruminates.  To each their own of course!

Do a little more research on UC in sheep.  I only know goats.  Don't know much about sheep.  But the people I know who keep sheep don't grain them (unless it's a ewe in milk), so I suspect there's a good reason why.  

Hi Jen,

Thanks for the info.  I had read before about grain and Male goats, but the issues were never spelled out as well as you did.
