Does anyone still feed these? Are they still in business? When I looked them up, the Facebook page was gone. 

Yes they are still in business. I feed them everyday and love them! We are a dealer for them as well. Their facebook page is still active. Did you look it up under Danco Forage?

I may not have used forage in when was looking. Thanks!

Yes I use the Omega Plus cube for my 2 older geldings.  I get mine from Wynnewood, OK and they carry both but I prefer the Omega as they do not have the oats and I have one gelding that does not need the oats.  Love them and have save a ton on hay but then my 30 year old cannot chew hay that well anymore.
