can anyone tell me what color these babys may be?

[rainefeather19128]

baby one is a pure whitefinch with possibly a faint tan touch to the feathers...unless it is the skin on its body.here is the main catch though,he or she has a pinkish beak.

baby two looks like a white finch rolled in dust bunnies or light brown sugar....something like that.his or her beak is a light grayish pink.

baby three i know is a normal gray.possibly male since i see a gray bar comming in on his chest and white and gray bars on the throat.they are faint but getting more and more prominent.

i'm betting that with the first two they could be
something with isabel coloring
pure white
pied
or continental cfw...just guessing though...any ideas?
