I kept one Coral Blue keet this year. It was hatched on July the 1st or 2nd. When it was approximately a month old, I moved it into my temporary introduction cage in the guinea coop. Today, approximately a month later, I opened the door to its cage and let things happen without watching or interfering. I did see it in the weeds around midday keeping its distance from the adults.
After herding the adults into the coop this evening, I went searching for the keet. It was sitting in some grass and very calm. I herded it to the coop (first time ever being herded), and it went right in without any hesitation. I was amazed that not one of the adults offered to peck at it. After gathering their eggs, I went back to the coop and watched it fly up to a roost and settle in right beside one of the male adults. I really was surprised that the male did not even try to peck at it.
It appears to have been a successful introduction. I intend to remove the introduction cage tomorrow.
