Instead of dropping the eggs which keeps others from spawning until they decay, press right trigger instead of left. You'll eat it and clear it off the world so more eggs can spawn. And any stone trap is easy, affordable and durable.
I got a level 150 lightning egg and I was so excited to hatch the egg...that when I went to put the egg down I accidentally ate it instead. :( ps4 users: R2 ISN'T GONNA DROP THE EGG YOU'RE GONNA EAT IT LIKE ANY OTHER EGG. REMEMBER THIS. LOGIC BEFORE EXCITMENT.
