I have a one month old buff silkie. I hatched buff orpington eggs and only one hatched so I brought the silkie in for company since it was so small compared to my LF hens born the same time. The silkie, Noel, instantly started "mothering" my one day old chick. Would that mean she would more than likely be a hen or do silkie roosters also do this?

This is her with the chick under her.
