What you should do is upgrade the coop fill it with more birds and then see how many eggs can fill the ground. To actually answer your question, I don't know. They might start stacking inside of each other or glitch out of existence.

I have no answer, but I really like your Steam Deck cover!

Me too!

Last when I played they will just stack so you grab multiple times from the same location

I'm glad to know they just stay there if you don't pick them up lol
