they can, but its generally a blip in the egg system and they normally take the next day off.
It takes roughly 20 hours to produce an egg. And Chickens do have a limited number of eggs inside them.
It is extremely unlikey that a hen will regularly lay more than one a day, most dont lay daily for more than a few months.
I'm pretty sure they more regularly they lay the faster they will 'burn out'
It only takes 14 hours to lay an egg.
