Coona eggs are nearly always laid on feathers. While they can be removed from this feather bed, the egg seems to grow better on it. They all have what looks like a string and beads wrapped around it; the kind of beads on it differ from egg to egg. These beads are very important to the egg and removing even one could cause problems for the creature inside such as being very weak, getting sick much more easily, or even dying shortly upon hatching.
A Coona's favorite activity is collecting feathers to make accessories with, usually the molted or dropped feathers from Perukey or Gobblers. Every year, around September to November, they can be found gathering them and bringing them back to their dens.
These accessories are very important to them. Whoever has the largest feathers seem to be considered the leader in their packs while the Coona with the smallest feathers is the lowest member. They are rarely seen without one but even more important is them is the string of beads they wear. It is the same one from when they hatched and one seen without it are likely very close to death. Nobody knows why their beads hold so much importance to them, although the Science and Research is working to find an answer.
