ah, you're right. Any suggestions for farms or anything that I can grind xp or money as a poorer player?

I'm not the richest player, so I decided to grind using a traditional pig breeding farm. I had 3 pig spawn eggs; placed two immediately in my about 10x8 fenced in area. One of them disappeared. I thought I placed them too quick, so I used the third one a few minutes later. Just like the first...
