Ok here goes, a little embarrassing but I really don't know. Where does the egg come from is it like any animal that gives birth through the "shall we say" birth canal? Or are the vent and the anus the same thing. I was gonna look but was afraid my neighbors might think I was a little strange. I asked my friend that has been raising chickens for over 20 years and he wasn't sure either. Please overlook the stupidity of this question, but I've always heard "the only stupid question is the one you don't ask. Thanks and enjoy the laughs.
