Might be because i took the pics on a more chilly night, i took a newer picture mid day, do they still look sickly here? If so i would have to medicate. I was going to proactively treat all the birds for mites before entering the aviary although if they are showing symptoms i might have to act faster (to or not to proactively medicate everyone beforehand?).
speedy birds, hard to take pics unless they are feeding:
