I have 12 babies that are 8 weeks old, and 5 of them are starting to develope beards. 7 of them do not appear to have beards. I only have 1 hen out of 6 that is not bearded, and my Roo is beared. Should I give these babies more time, or is it safe to say that these will not be bearded? I need to cull(re-home) due to space limitations, and will start with the beard-less ones.
