Grandchild being in this case a major understatement, but seriously, chickens are amazing. Amazing and amazingly weird.
Take the whole issue of eggs for example. It takes a hen about 26 hours to produce an egg. But when the hen sits on a whole batch of them – up to a dozen – they all hatch around the same time, not at 26 hour intervals for a fortnight. (Assuming a rooster was involved prior to egg-laying. Otherwise no business results and the hen gets bored after a while and wanders off.)
