First of all, how'd it get broken? Was it because someone rung it's neck? If so, this sometimes will cause a rip in the neck hide and tear the feathers in the same area. Depending on where the rip is, if at all, will determine if you can hide it or moun tit so it's facing the back.
If it looks good to you, it will probably be a good mount.
