The shortbody which I thought was male and later realized was female? Or the normal Green Texas which I thought was female but was actually male?
If you meant the short body I had no idea if it would be fertile or not, at the time I still thought it was male so I was definitely questioning if it was fertile or not. It clearly has a lot of Texas blood so I figured it was worth a shot. It ended up being a female so the question is moot.
If you meant the normal Green Texas, no matter what sex it turned out to be I always knew it was fertile because it's not a hybrid.
