I have had a business or two, and written my share of ad copy. So I suggest....
.... leave out the entire sentance starting with Happy chicken... you cannot really say what other chicken people are doing. In oregon we have foster farms, a large grower that is using the same aurgument.
It would give you more space for your logo ,,, and make it more simple, sound a little less preachy..... beware of promising anything...
I know you are proud of your product,,, but let it speak for itsself....
I like the just logo, perhaps that would be the cleanest label..
(I have had organic chicken that tasted terrible.... it happens.....)
good luck !
I really wish you the best, keep us all posted.
