I'm not too sure... They may be a week or two older but not too much older. Te people I got them from didn't know too much about it. They forgot when they hatched and everything. It is very possible it is older... Maybe 14 or 15 weeks. I'm not too sure. I think I'm going to weigh them to see if they are around the 5 or 6 pound range, that may allow me to get a better age range...
When we picked them up, they could easily jump a foot off the ground. A week later they could fly about 3 feet into the air.
It has been 12 weeks since we had got them and the people we picked them up from said they don't know how old they were by they are guessing 1 week.
My baby black stars are 13 week and just started jumping a foot off the ground, so it is possible that they are around 15 or so weeks...
