Can't wait to hear more! Just an FYI, there is not quite such a thing as "Pineapple Conures," what you most likely have are Green Cheeked Conures with both Cinnamon and Yellow sided color mutations, the combination of which is called Pineapple. But Pineapple refers to the color, not the species. So they would be called Pineapple Green Cheeked Conures, like I have Blue Indian Ringneck Parakeets. Indian Ringneck is the species, blue is the color. I have also seen some pet stores sell Sun Conures, which are a completely different species sold under the label "pineapple conure" which is entirely incorrect.
I can't wait to hear about their progress! Where did you get them? Do they get along with each other? Best of luck!
