Briana I've thought about this a while now and am just curious, why are you wanting to raise them together? Personally I have never imprinted two of them together though I have done a bunch of sharpies and sparrowhawks over the years.
Just wondering what the good and bad consequences might be. Are you imprinting them together, or with you and or your husband also involved? Multiple imprinting on several things, like each other + humans + dogs+cats+etc? Just curious.
