Here's my transcription of the sound file at Honking Duck:

WHO BROKE THE LOCK ON THE HENHOUSE DOOR
(As sung by H. M. Barnes & His Blue Ridge Ramblers)

1. I went down to the farmer's gate.
I blowed my horn both soon and late.
The farmer's dog wouldn't bark or bite,
But the son-of-a-gun could read and write.

CHORUS: Now, who broke that lock? Well, I don't know.
Who broke the lock on the hen house door?
And I'll find out before I go,
Who broke the lock on the hen house door.

2. Went down to the hen house on my knees.
Thought I heard old Bruno sneeze.
It was an old rooster saying his prayers,
Telling his love to the hens upstairs.

3. The meat's upon the goose, but the marrow's in the bone.
The devil's on the hillside. Don't you hear him groan?
Turkey's playing seven-up on the melon vine, [seven-up = a card game]
Goose chewing tobacco and the duck is drinking wine.

4. Said the barnyard rooster to the barnyard hen,
You told me a story and I know when. [story = lie]
You said that Sally made her cake all dough,
And never mind the weather so the wind don't blow. [so = as long as]

5. Said the barnyard hen to the barnyard rooster,
You can't hear near as well as you used ter.
I said that Sally had a dress so cute.
We could trade her our feathers, get a nickel to boot.
