They are the oldest ones I have. They are only one month old. I ordered them from Priscilla Meinholz as day olds. There are 4 of them and 2 dewlaps that I hatched out about 1 week after getting the sebs in the mail. I also have 1 younger Seb that I hatched out and 4 even younger dewlaps that I received from California as day olds. Those are kept separately.
