HI Cynthia no I used to when they free ranged though. Now I keep it covered with another bucket on the outside of their coop. Unfortunately the deer like it and if I forget to cover it right after feeding they will munch on it. Every morning and every evening they are there to see if I forgot to put the bucket on. They do clean up any I may have spilt.
At this stage it's new from the brewery so not fermented yet. I think it does some fermenting as it ages though. There is approximately 4 different grains in the spent grain depending on what type of beer is being brewed. The majority of it is barley. This grain has been put through the malting process which is the controlled germination of the grain, drying and kilning or roasting of the grain to achieve the different flavors of the beer. The grain is sprouted and at the point of root emergence dried to stop the growth. Then hot water poured/steeped through it to remove sugars. That's when I take the grain from Peter my brewery friend. Yes another Peter lol. Then he takes that sugar water called wort, and makes the beer out of it. The wort is very very sweet.
I trade him a dozen eggs for the 12 buckets of grain. That way I'm assured of getting first on the list for the call when he's brewing. I have competition for this grain so far the pig farmer hasn't offered any compensation for goods recieved so I win.
On the sunflower seeds I don't think a handful a day will bother them.
Is the calf mana a crumble?
