I went looking for sheet music to the songs described above, and I haven't found them yet, but I did find this one. It looks like Frank Stokes' song is an answer to this one:

DEM CHICKENS ROOST TOO HIGH
(Fred. Lyons, c1887)

Go and tell Uncle Zip and old Aunty Sue, dem chickens dey roost too high,
So dar's no use to git up dat barbecue. Dem chickens dey roost too high.
I went to a coop way down in de lane, and creeped in de doah very shy,
And grabbed for chicken, but I grabbed in vain. Dem chickens dey roost too high.

CHO. Adieu, farewell, sweet chicken meat, goodbye.
Oh what will us poor darkeys do? Dem chickens dey roost too high.

Dar is no more fowl fur da poor black man. Dem chickens dey roost too high.
So put out de fire and hang up de pan. Dem chickens dey roost too high.
Spring chicken is good cooked most any way, but gib me a nice chicken pie,
But dar's no use to talk, and so all I'll say, dem chickens dey roost too high. CHO.

No more I'll steal in da old chicken coop. Dem chickens dey roost too high.
Nor ease my palate on nice chicken soup. Dem chickens dey roost too high.
De ole turkey gobblers am a-getting smart, and de chickens am getting very shy.
Oh, it's almost a-broken my poor black heart. Dem chickens dey roost too high. CHO.
