Hi there.....please bear in mind that your pictures are not very clear and I am not an expert.....Someone more experienced will be along soon....but I would say......the first three are girls, and the last picture definitely a boy.. Beautiful budgies, how old are they?

The weird part is that dove and lemon they courtship together feed each other and groom each other and according to my dad lemon tried to mound Dove and they are interested in the nest box
