i know that silkies generally get to be around 10lbs - sometimes 12
and yorkies are typically between 4-7lbs so it isnt alot bigger
they look VERY similar... someone i work with has a silky and it looks very similar... a lil greyer and 11lbs but not alot diffent
plus you dont know which gene will be dominant so it may look all yorkie esp since the diffences are slight
good luck hope this helps
