LUTINO,LOVE BIRD,ALBEINO. 1) If u want to check male-female of the above birds without touch, u put CORN upper cover in the cage, only female cut it in a very think stick then put her feathes and go into her nets, then put it down and again do the same. Male never take this. 2) Catch one by one and check lower bone gape, female has big gape n male is small gape.
