I have 4 Silkies that I purchased from MPC that are about 12 weeks old now. I have 2 buffs, and 2 partridges. The partridges are very full, fluffy and have very full top knots. The buffs, not so much. Not only are they scrawnier, (could be cause they are not as fluffly looking) but one doesn't even have any fluff on her head at all! The other has a little. I realize that these are hatchery Silkies, so I wasn't expecting perfection, but these two Buffs look like they are Silkie mixes. They do have the extra toe, some feathering on their legs and feet, as well as the "silkie" type feathering on their bodies, but that is it. Any hope that they will develop more fluff as they get older? Not sure if it matters, but the two buffs are way more scared of me than the partridges. Always have been. Thanks!
