You might want to check with Coopa Cabana (Gail) or ShysCreations (Shylee) they both have bantam Cochins and Shy has Silkies if those interest you.
Sorry, I didn't hatch thru the winter as no one was laying, so I won't have anything available until later this summer. I would definitely get in touch with Shy and see what she has available - she usually has some great stock available in either breed.
