Much as I adore silkies, you need to let your daughter choose her breed. Certainly provide some oversight, but let the choice be hers. There are many breeds suitable to young children, not just silkies. At six, she might prefer a smaller bird that is less of an armful for her such as a serama, a dutch, and OEGB or a d'uccle or d'anvers. Or she may adore the fluffiness of silkies.I don't know much about silkies but my daughter is in 4-H and she is 6 and a half and small for her age. I was told silkies are calm bird and would be good for her size to show in the fair. I would like to find someone close that may have some that I could look at and see how they are. I live in Williford Arkansas. I would like to see them before I get any.
My six year old granddaughter is drawn to the sleek looks of moderns and serama. She prefers their smaller size, too.
