Blue bird, has affection but flies and sometimes bites, and I think it's a female. Yellow bird, timid but doesn't bite, and the seller said it's male. The blue one is in excellent health, thank God. The smaller one sometimes has droppings stuck underneath, I don't know why, but the rest of its health is good. New setup. And the second pair, the white ones, I bought them as a pair that are accustomed to each other. They have laid eggs before, 6 of them, but unfertilized, and the same with their previous owner, sometimes they laid fertilized eggs and other times they didn't. And the female is currently in the nesting box, it seems she will lay eggs again. Regarding the male, there are memory issues, see my previous ad for details.
