Minecraft - make sheep reproduce completely by themselves in a stable?

Is there a way in Minecraft for sheep that have been lured into a stable to reproduce on their own? Or is it possible with a hay bale or something similar?

No, I don't think it works, because you have to click on the sheep to multiply them.

In Minecraft there are no possibilities to reproduce animals (except villagers) automatically.

But with a mod it is possible, unfortunately I don't know what its name is. Maybe curd
