I think it's regional differences...

Chook chook chook chook chooken, lay a little egg for me
Chook chook chook chook chooken. I want one for my tea
I haven't had an egg since Easter, and now it's half past three
So - chook chook chook chook chooken, lay a little egg for me.

Don't know whose song it is, but my mother used to sing it.

Never heard the chicken thingy but must say its enormously good fun.!!!!
It's not a rhyme obv but one of my favourite sayings of my late mother ( who was actually a very sweet lovely woman )was that someone was
"neither use nor ornament " which , when you think about it, is pretty thoroughly damning......
Re chickens my OH sings a little ditty
"chick, chick, chick, chick, chicken...... lay a little egg for me"
don't know where he got that.
Scunthorpe.....
my friend's mum had a lovely saying about her daughter(my friend)
" she's a rum lass.......I don't know where she gets it........"

Vito ! we are from the NW originally, I well remember Shirley Valentine saying chips and egg, thinking, what? its egg and chips, who wrote this? of course it was Willy Russell, NW born and bred, also wrote the screenplay.
I never heard ‘chips and egg’ before or since, it just doesn’t scan, drove us mad too.

The standout regional differences Ive noticed are bread and cakes, as in barmcakes/baps, breakfast rolls/cobs, oven bottoms/muffins (of course now my brain has seized so that I cannot think of any others, help!)
On visiting friends in Yorkshire, into the chippy, friend ordered a ‘breadcake’ I thought, that is a bap!

I say, the same as you, Arden and Chicken, but always egg and chips. I'm from East Anglia, my family Suffolk/Norfolk .
Shirley Valentine said chips and egg,first time I'd ever heard it, drove me mad 😀

I have never heard this expression!

It is kitten in the version that I know, but that's because that's what it said in a nursery rhyme book that my son had when he was little. I didn't know that particular rhyme before that, so it has nothing to do with the fact that I am from Yorkshire.

Egg and chips

lizzypopbottle,
I say 'bread and jam' but jam ^on bread'.

Jam and bread (NE) or bread and jam?

I am in the S E, one of my Granny’s always said pardon Mrs Arden, there’s a pussy cat in your garden

This has been passed down the generations and our young GC find it hilarious.
