When I brought the budgies home, they were quite young and I was hoping I had two hens and two cocks. But, I was only half right. lol Chris and Kit turned out to both be boys.. and now they are so bonded to each other.. They groom each other, feed each other, play together all the time so I don't think I have the heart to separate them..lol They just can't figure out which one is gonna "pretend" to be the hen..lol It does seem that Kit is the more "bossy" of the two.. Petey and Tillie did turn out to be a pair and at a year old now, they are showing interest in each other and Tillie has been checking out the nest box this past week. So I am "guardedly optimistic that perhaps there may be some eggs in their future..
