Have a mod where you need tons of rotten flesh? Well, I have recently thought up a way to farm rotten flesh. It takes some work but if you need TONS of rotten flesh or if you want to watch some villagers get eaten, try this.

1. Craft yourself a lead.

2. Find a village and kidnap a bunch of villagers using a lead.

3. Trap the villagers in a pen and fill it with wooden doors. The wooden doors makes the villagers breed. Make sure you have a gate or iron door to the pen or the villagers will escape.

4. Go look for a name tag. You find name tags in dungeons.

5. Use your lead on a zombie and make a special pen that is not very close to the villagers for the zombie.

6. Name the zombie with your name tag. That will keep it from despawning.

7. Whenever you need rotten flesh, use a lead to drag a villager in the zombie's pen. After the villager is infected, just kill the villager and you got some rotten flesh. Don't kill the zombie you named. It's hard to find name tags.

Hope you have fun messing around with this!
