automatic popdoor

[willkatdawson]

Does anyone know where to buy a automatic popdoor for my hen house to let the hen out in the am and shut the door in the pm? The ones I have seen on line have all been in the UK. They are on a timer or a light sensitive system. Are there any for sale in the US? I hate to order from soo far away in case I have any problem and also I hate to pay the extra shipping.
Thanks

Foy's Pet Supplies sells the same unit they're selling in Britain. They're located in Beaver Falls, Pennsylvania.
