Well, I moved my white "pair" to a flight cage (just had them in it) and the other pair into my dove's flight cage. After a short while, they all started acting funny. I assumed that they just had to get used to the new cages. Today, one of my whites was dead, and my cinnie RB roo was dead. I hurried up and pulled the last white male, and the female and put them back into one of the old cages. They took a few minutes, then were running around, chirping and drank a LOT of water and were eating shortly afterwards. I'm just glad that they went back to normal so quickly, but, what's the deal? Yes, I was aware that they might act funny for awhile in a new cage, but, to actually die? The food in the dishes seemed to have been eaten, though I know some was kicked out (maybe all, if they died?) The cages were BIGGER, and the one was in the same spot that the smaller cages were put in.
