Setting up a household that includes flock members from different species can very naturally bring up some differences of opinion.
Say one flock member is small and feathery. He prefers everything to be very open and spacious with no (zero, zilch) obstructions in line-of-sight.
But then say another flock member is round with a shell and hails from a deep forest environment. She prefers a living environment that might best be termed “cozy clutter.”
For this flock member, any line-of-sight is too much line-of-sight. Out of sight is much better. Safer. And infinitely more comfy.
And so the flock members get to work customizing their respective corners, using the materials at hand to create the most naturalistic and homey habitats.
