Audrey,

I have had very good success keeping young goshawks in the house by utilizing a kids plastic pool and canvas painter tarps. The tarps can be washed and absorb the mutes, and the low sides of the pool catch 95% of the slices. Some falconers, abhor the idea of tying down a young raptor, but I had no problems with this as long as you tie them down very early on, before they know any better. Without living with an imprinted eyass goshawk through its first fall, I think that you will have a very hard time obtaining the results that you probably desire.
