HI, these little peeps are so small, even at 7 weeks. It is hard to believe any of them could be roos however, the white and brownish one play spar while the little black one hangs mostly with the mom. Is it too early to determine their sexes? Also, that white one that developed a black speckling... has anyone ever seen that coloration in a chick before? What type of bird could that be a characteristic of? one week old 7 weeks Thanks for your guesses. I have looked as many pic posted on this forum thread. It sure would be nice if folks would follow up with pics of their peepers once the true sex is determined when they post pic for guessing sexes. Wouldnt that be helpful to see the progression!
