I am curious: what "hormonal issues" exactly are you talking about?
The fact that they pleasure themselves (I think that is what it's called

)? The fact that they may want to build a nest and lay eggs and have a stage in which they are a bit "high-strung" because it's normally the time that birds have young ones? (I don't know but I think that goes for all kinds of birds.) The fact that some of our quakers get more light than others? Maybe simply because of geographic location?
I guess only those of us with all sorts of birds might have an idea whether those things are different for quakers because they're all different to start with (like humans). I have two qps and they are very different.
