Are you sure about that? I was told by the pet shop owner that these are 3-4 months old. Also that photo isn’t that old. I took that picture the first day I got them.Especially since this is an old photo, they're definitely not 3-4 months. All the birds in the photo are adults. Once they reach adulthood, it's nearly impossible to tell their age by sight, so any answer would be pure speculation! They are all definitely older than 8-9 months of age and are most likely older than that.
