I got 4 sapphire gem chicks. They all are suppose to be the same age but 2 a about 1 week older. The.older ones are about 6-7 weeks old. I have my suspicious that I might have a roo on my hands. There was not a spot on the head or wings when it was fluffy but looking at the tail feathers compared to the others has got me thinking. Any help will be appreciated.
