It takes a bit
more than 24 hours for each egg to make its way
down the tube, and during the journey is when the

the chickens, like birds, don't just stop and drop
an egg. It's quite an ordeal I think. They
definitely act broody and nasty when it's time and
can barely be enticed out of a nesting box, even
with food, if they are about to lay. They stand
up when they finally lay. And if they are
excited, they squawk and crow. If they are really
broody they will sit forever on the egg. I'm sure
it's all hormonal.
They do. Birds, like other vertebrates (excluding
mammals) have a cloacae out of which their urinal,
rectal, and reproductive tracts open (mammals have
just externalized the cloacae so that we have more
holes). Eggs come out the reproductive tract.
