Does anyone do this?
If you are, why are you feeding it?
Do you feed it the way it is, soaked or boiled?

I have seen most people feed it soaked but then I read this:

"Contrary to popular belief, flax seed doesn’t need to be soaked or boiled before feeding.
The belief that flax needs to be soaked or boiled before being fed comes from the fact that the seeds contain components of cyanide, which is toxic.

However, the two components of cyanide that are found in flax are stored in different parts of the seed, never touching each other, and therefore never able to create cyanide.

Any contact with water (including boiling or soaking) brings the two components together, creating cyanide — so the "prevention" to make the seeds "safe" actually is more dangerous than feeding them unboiled or unsoaked. (Note that saliva, stomach acid, and other digestive juices break the two components up before they could ever become joined and create cyanide within the horse’s digestive tract.)

Soaked is actually one of the most dangerous ways to feed flax, as the cyanide is created and left standing in the water and flax.

Boiling changes the cyanide to a gas form, thus removing it from the flax. However, it also destroys all the fatty acids, effectively removing the entire reason for feeding the flax in the first place.

Another consideration is that when you remove the lid from the pot, you are going to be the one ingesting all the cyanide.

Thankfully, the amount of cyanide created when boiling flax is very small…in fact, we take in more cyanide in our daily lives through our food, water, and the air we breathe than is found in a cup of boiled flax. Cyanide is also very quickly removed from the body and is not stored in the body tissues — so if you don’t die immediately from cyanide poisoning, you’re going to live."
