One of my Mille Fleur D'Anvers is very tiny as well, hatched the same day as the others. So super tiny!
BTW, Aubrey, I swear, I now think I have only two pullets! Both porcelains have pink combs and three of the Milles. They are going to drive me nuts before it's all said and done, but I'll add those two other girls to that coop and if they are not aggressive breeders like you mentioned, then maybe it will all work out okay. I'm in no hurry to get rid of even one of these since I waited so long for them! The standards, on the other hand, I want to get rid of my extras the minute I know who is male and who is female and I'm close to that now with most of those, at four weeks of age.
