It also depends if dads split pearl or an actual pearl that has lost his pearlings. if he is actually a visual rather than split then yes all pearl offspring will be hens and greys cocks.
Being split or visual has no bearing on whether the baby is a boy or girl. Girls get the pearl gene ONLY from dad. This means dad has to be carrying the gene and girls can ONLY be visual pearls. Girls can not be split to pearl. Because mom is not a visual, any pearls are girls, meaning dad is split. If there were any cinnamon babies, they could be either or, because it would mean dad was split to cinnamon and was carrying that gene as well. Cinnamon is like pearl in that hens can only be visual, so to get a boy cinnamon or pearl, mom has to be visual and dad has to be either visual or split.
Any way you dice it, the pearl is a girl. The other baby is unknown for now.
