I would say there's no reason to feel bummed, value and worth of something can be totally subjective at times, and to me it sounds like for you, they do have value. I produced two animals this season that to me were more valuable than what they would sell for...so they are still sitting in my rack. What I will say though, is put some thought into what you're going to do with all these animals, how much sense does it really make to breed a pastel male to five females (if that's the direction you sound like you're going here). There are a lot of breeders moving out single and double gene proven males at shows to replace them with something else, either more genes or newer ones...animals that have more than paid for themselves, will likely be out of future breeding rotations and it's worth it to give someone a break on the price to free up the cage space at home...just something you might want to think about.
