we have never raised ornamental chickens before. we have some questions about silkies, which we were thinking of getting next spring. 1. Are they cold hardy?? will they make it through shipping and winters? Will they be OK with hot summers?? 2. Are they regular layers? we don't need them to be, but it would certainly be nice to know. I have heard they set. 3. Are they kid friendly? They MUST be friendly to be around. 4. Do the colors make a difference in friendliness or anything? we are thinking of getting black ones. Do you have any color suggestions???? please respond if you have any idea of the answers. thank you!!
