so a lot of people are saying to use cacti farms or cobble generators to get enough for a chicken spawner, but I would also recommend egg profit shops, i have an egg profit shop on my is (/is warp muffinyboyhalo) that does $10 for 50 eggs, it's actually a realllyyyy fast way to make money for both. mine restocks fully after about 5 minutes, so you could literally be making like $5k+ every 5 minutes
now that's a really big estimate, but it would be the fastest way to get enough money without having to do much since this season profit shops are working
now just make sure to not get scammed!!!
