A pen useful for raising roosting fowl from the chick stage through maturity. The pen includes a floor which is pivotable between a first, closed position and a second, open position in which eggs from the fowl can pass out of the pen. The front of the pen includes a feed trough, the wall of which is provided with apertures permitting chicks to enter the feed trough when the floor is in the closed position. The apertures are blocked off when the floor is in the open position.
