I would tell her how you feel, tell her you want to get into showing, and in comparison to this other buck chase just isnt up to the standards. If you think about it yur buck is half of your herd, he can service a lot of does including outside does. a single doe will produce on average two or three kids a year, how many can your buck produce? My yearling had twenty this year....I dont flinch at paying eigh or nine hundred for a buck, he is the one that is going to improve on your does. If your does are better then your buck you are taking steps backwords in improvements, you want your bucks to be better then your does. One buck isnt going to fix all the faults but he can do a great deal of fixing faults.
You will also get more out of a kid out of the other buck then you would out of chase. as much as you like him and want to see kids out of him and lyric, i think you will have better kids out of the other buck. Remember that it costs the same amount to feed the bucks, but in the long run you are making more money off of the nicer of the two bucks. Im not trying to push you into anything, just telling you what my personal opinion on the matter is. taking into consideration the cost of feed these days, you really need to try and get something out of your animals. I know they are pets and you love them to death. But several years ago i made up my mind that if im going to have these animals they might as well at least help with the cost of their feed. Paying for a nicer buck you are going to get nicer kids and in turn kids that are easier to sell, kids that are easier to market and kids that will do better in the ring bucket or whatever you want them for.
I hope this all makes sense.
