I'm not certain, how old they are. Owner told me he got them at 3 months old and he's had them for about 2 years. They're both about 9-10" disc. I feel that they are a little older than that. Could be wrong though. Currently in a 125 =( I have a 210 in my barn but my floor won't support it. In the process of building a house that should be done in 4 months or so. As soon as I'm moved in will be building a 7'x4'x2' playground for them.
Are these the 2 that came from Ubomb? If so I believe Tazjack on here could tell you how old they are since she should have been the original owner of them.
