Thank you everyone. They went missing on 5 June. I have heard from one person who thinks he may have sighted the ringnecks, including the female! He says he has a yellow bird hanging around with the flock he feeds, but he think it may be a previous yellow bird that he just hasnt seen for a while. The other possibility is that the previous yellow bird being in the flock helped them accept this new one, who could be my Lee. Sadly, no word at all on any of the others through any of the outlets, facebook, craigslist, humane society, vets, pet stores, fliers, police, internet forums... but my heart has been warmed by the support I have received. At first I thought it might have been a prank or kids messing around, but a week later with no word on six escaped birds... well, I have helped recover enough birds to know that I should have found SOMETHING on ONE of them by now; theft seems the only logical answer, especially as Lacey was clipped. My heart hurts, I feel like I'm living in a nightmare. My only consolation is that if they were stolen, they are most likely at least being fed and watered, and are not out there facing the elements alone. Again, thank you everyone.
