Is It Possible to Pose a Rag doll

There always seems to be something interesting to ask. But here is a problem I have that is ragdoll or dead replacement related. now my situation is this; I have an Alien Zombie munching down a chicken inside of a chicken coop, when my FPS player shoots him and he dies on his dead replacement he ends up stuck through the geometry of the chicken coop roof, which is kinda creepy looking because he just sort of hangs there "twitching"... but it's not what I want to happen obviously. I think it's because the "Rag Doll" starts off in the "T-Pose" and because the chicken coop is sort of a confined space that when it get instantiated it intersects with the chicken coop.

Is there a way to "Pre-Pose" Rag dolls or is there a way to fix issues like this?
