How long does it take for Pokemon to breed in gsc?

I sent a female feraligatr and a male larvitar to a daycare so I could get a totodile with rock slide, but it's taking forever for them to breed. I left my game on for 2 hours, but they still haven't bred. Tips?

Totodile can’t learn rock slide.
Totodile can learn Rock Slide as an Egg-Move in G/S/C: https://pokemondb.net/pokedex/totodile/moves/2
Oh, oops. I just looked at the gen 7 movesets...

It depends on the species and ID of the Pokemon you are breeding.
The process is different and more complicated in G/S/C than in other games, so pay attention for this next part.

In G/S/C, after you give both Pokemon to the daycare man, there exists a pre-calculated number based on how compatible the Pokemon are with each-other, we'll call this number "A". After this pre-calculated number is determined, another number between 1 and 255 is is randomly decided, we'll call this number "B". For every step you take, "B" is subtracted by one until it hits zero. Once "B" hits zero, another random number between 1 and 255 is generated, and we'll call this number "C".
If "C" is lower than "A", then you will get an egg.
If "C" is higher than "A", then you will not get an egg. If you do not get an egg, then this process repeats until you do.

The (estimated) pre-calculated numbers (or "A") goes as follows:
If the Pokemon you're breeding are the same species but have different IDs, the number is 127.
If the Pokemon you're breeding are the same species and have the same ID, the number is 96.
If the Pokemon you're breeding are different species and have a different ID, the number is 63.
If the Pokemon you're breeding are different species but have the same ID, the number is 32.

Basically, you have a higher chance of getting an egg if the Pokemon you're breeding are the same species and have different IDs.

Good luck, my fellow Pokemon Breeder!

So basically, if i just leave a rock or something on my d-pad and leave it on for a few hours, eventually, they will breed?
A little less than an hour actually, but yeah basically
Assuming you don't hit any obstacles to block your path, then sure, the rock thing would work out. It may take a while but it shouldn't take too long. Just be patient and you'll get it soon enough.
