Our baby parakeet left the next box this past weekend while we were out of town. It is a yellowish green color with a little bit of blue on its tail.
...the yellow parakeet in the box is the mama (yellow and blue make green, haha), the blue one growing feathers is a sibling. We are assuming that the eggs were laid at different times, thus the difference in age of the babies. We are also assuming that not any of the other eggs are going to hatch.
