How many to produce total to cover everything you'll ever want eggs for? Ummm... I dunno... in one of my saves, just entered year 4, I have almost 200 eggs in my fridge, and not too terribly long ago I made 200 pink cakes (which each require an egg) because I needed to cook 100k in food for a reward (late game stuff). Then there's all the other eggs I've turned into mayo over three years. I'd guess... 3 years... with 112 days in a year... I've had 5 chickens most of that time... over 1000 easy if you play like me, though that means I've produced roughly 1500 eggs and only have about 200 right now, so I've used 1300 so far, and that doesn't count eggs other than chicken eggs.
