I just introduced 2 babies to my broody silkie. She is a great mum. She took them at the first sight. Now, I have a nice and multi-breed family, a silkie mum with one pekin baby and the polish baby.

Generally silkies make the very best broodies. Sometimes silkie roos even help out to guard the chicks, and keep eggs warm while mama is out taking care of business.
