As Siân says, it is difficult to be objective from up-close. I'm not too keen on that penultimate verse either,
One alternative could be

I have a hen and cock'rel
A cow, and fatted swine
My wife is ever at my side
And so, we're doing fine.

Whilst avoiding the 'doing alright' cliche, I am worried that people running lines together will get the wrong sense from "A cow, and fatted swine, My wife..."

As before, comments and suggestions are heartily welcomed
