Trying to remember...

I can't think of the name of a fearnet I watched last year on demand. It was a british one that started with kids driving to one of the kids grandfathers house and his grandfather was experimenting with birds. The birds ended up becoming zombie birds that get out and infect many of the surrounding residents and the kids are stuck in the house being horrified by the zombies. Also, one of the chicks had some cannons and in typical fearnet on demand fashion those fun bags were shown in the sex scene where the chick ties one of the guys to the bed and rocks his socks off.
