No one really buys villager eggs anymore. If you joined around a month ago, you could make a lot of money. I suggest wolf or ocelot eggs.
You can get a mod to. You don't have to stop selling them, people still buy them, but I would sell other eggs to.
Remember that eggification in the wild costs 100r. Now you can't breed villagers in town, the price will probably rise. I think 60r is quite reasonable to be honest.
