I am hoping to retain her. Sierra has also gotten attached and I'd sold Sierra's 1/2 shetland riding pony years ago and we hadn't ever replaced her. Sierra has since taken driving lessons - both single and paired (only a few times w/ a pair, but enough that she can help with hitching and is a confident driver) - so I feel it's well worth it to retain one that she is interested in/claims as her own. It also means getting a little more help (?!?! shouldn't, but..) If pressed, I will put a price on her, but it won't be a small number and most would swear we wanted gold.
AS to whom "Chylly" would drive with as a pair or in other multiples, that really depends on her finished growth and her mature personality and movement. We have lots of chances of other matches for her as well - "GG" (Chylly's dam) isn't the only silver or silver tobiano that can/will produce chestnuts now - especially if I don't use the mares that are homozygous for black (all by the stallion that sired some problems).
"Chylly" will fit well with our continuing breeding program - well into the future. So would have "Kava" the other filly that Sierra had taken a shine to last year, but things happen... But that was the plan all along when I was trying to plan a future for our breeding program and continuing the lines that I've chosen. I'm not perfect and I'm still working on it - it was hard to deal with the "genetic anomaly" a few years ago. It's much harder to do now (producing foals), with the current market. I don't have the funds to breed a lot, can't keep them all & can't always go to shows to get our breeding program out in front of folks and while it was exciting, I didn't really like showing. I AM/WAS happy that foals from my own breeding program did WELL in the ASPC ring - open and Futurity programs, for the two years I was able to send ponies out with pro trainers to shows. Now, if we can do something with the driving aspect, that might be different - at least in the open driving venues - not just ASPC/AMHR.
I'm still working on how to tie FB and other media into our advertising when I don't want all aspects of my life on the internet...
