Why isn't my Espeon breeding?

Question

I am using Ultra Moon and I am trying to get an Eevee using my Espeon (M) and I tried breeding him with my Ditto. I was told they didn't get along well. So I switched the Ditto out for a Fomantis. It didn't work either. So I tried an Audino. And I found out that it didn't work because the Audino was male. So I tried a Mimikyu. And that didn't work either. I did some research on the site and I found out Fomantis and Mimikyu didn't work because they were in seperate Egg Groups. But I only want to know why Espeon didn't breed with Ditto.

I have never heard of something like this.

Eggs will appear more often if you have the Oval Charm, and if the Ditto has a different ID than your Espeon's ID.

Speed up the process of waiting by running with Tauros in that square pasture. (This place: https://i.ytimg.com/vi/Ib0i_1Nv71Q/maxresdefault.jpg )

If they don't get a long well, they will still breed. It will just take longer. The egg has a 19.8% chance of being made every 256 steps you take, so just keep walking!

@Pokemon Guy What do you mean by "Different ID"? Every Pokemon has a different ID. Do you mean OST?

---

@Espeonage I think he means OT

@MoonlitMadness That's what I meant. I was listening to a Video Game OST while writing that comment. Ty.

Answer 1

Now that I know exactly what you're asking I can answer this. Pokemon that are a different species and have the same trainer will only have a 20% chance of producing an egg (without the oval charm), which is why the game says they don't like each-other much.

That wasn't my question.

---

But you asked hy they did not breed. They would have bred if you let them stay together longer in the daycare

---

I asked WHY didn't they breed. Not ADVICE to make them breed.

---

Th reason they did not breed is because you did not wait long enough

---

Moonlit is right, sometimes it can take a long time to get Pokemon who don't get along well to breed. He/she is telling your your mistake, thus providing you an answer, not intending to offer you advice in lieu of an answer.

---

What I mean is "Why they refused to get along." not literally why they didn't breed.

Probably could have made more clear in the oirginal question
