We had two 14-week-old APA Ameraucana juvenile sisters and one died. We immediately got another Dominique chick to replace the lost pullet. The juvenile Ameraucanat got along with the Dominique chick letting it sit on her back and preen her face muff. Ameraucanas are wonderful tolerant birds. They would both fall asleep together on our lap. Both were in-house and I only put them together when I could supervise. If the Dom chirped in stress the Ameraucana would come running to see what was the matter. Flock birds instantly.
Unfortunately at 19 days old the Dom suffered a sudden seizure and was gone right before our eyes. She exhibited no symptoms except a little nibbling at her right foot just before roost. The next day the Ameraucana came looking for the Dom like she did every morning but there was no Dom. These birds formed a flock bond. Poor Ameraucana lost both her sister and the new Dom. We immediately started socializing her through the fence with the older flock as she really wanted to be around other birds and it was too late in the season to get another replacement chick friend.
You're correct about pet birds - they should be kept at minimum in pairs. We always kept our English in pairs. My daughter likes to keep two dogs also since they are pack animals.
