I have three babies. They are all four or 5 weeks old. I have a barred rock which has almost all feathers and no fluff and two mille fluer bantams with most feathers and still a bit of fluff. I would LOVE to know if they are roosters so that I can get rid of it before we get too attached and so that I can replace it with a hen before we have to put them all outside. Otherwise the new baby will have to stay in the brooder alone - since it will be so much younger. What ways can I tell if they are girls or boys? Also, we hold them everyday - but they still seem so scared of us and are not impressed with any treat we bring.
