I found this little lavender keet in the corner of the barn alone. It had apparently hatched out under Estelle (Spangled English Orpington) earlier today and gotten out of the nest somehow. I picked it up and put it back under Estelle, and stood back aways and watched. It was about two minutes later she reached underneath her feathers, grabbed the baby by the back of the neck and yeeted it acrossed the stall! What a witch! Poor baby hopped/ran back to the corner where I initially found it and hunkered down. I guess that explains how it got out of the nest in the first place.
Now it's safe and in a brooder box with the royal purple keet that hatched out in the incubator yesterday (THAT one kept playing lawn billiards with the rest of the eggs, the brat!).
