We have 6 silkie chicks that are 6 weeks old now and ALL have spiky feathers sticking up on their heads. We are worries that this is a sign that they may be roosters since ALL our other silkies that are hens had vaulted skulls and rounded heads. Does anyone know about this?? I know it is very hard to sex silkies to begin with but there are a few things that may help such as the spiky hair. Although I thought that because all our other silkies are white and the new baby chicks are partridge and buff maybe that has something to do with it??? Please let me know your thoughts!
