I've noticed that Amelia has been showing her robin's egg blue colors for a little while now while stalking the ground so I did the usual and got her nest ready. She hasn't seemed to lay any eggs as of yet, but suddenly last night she turned dark brown with green and bold orange spots. This is the first time she has ever turned this color! I know this is a normal coloring for female veileds but she is the only one in her cage and she seems to be snapping at anything and everything that goes near her cage.
My question is, I thought they showed this color when they are not interested in mating with a nearby male and also when they are pregnant. Since she's doign this and she is by herself, should I be concerned about her being stressed about something?
