I know that the males get around 36oz. and the hens get around 32oz. but how tall do Silkies get? I know they are bantams, but was hoping someone could tell me roughly how tall they are, and how to introduce bantams to standards. I have 39 chickens that are almost full grown and the introduction of the 24 to the 15 went off without a hitch. I had them separated by a fence in their brooder box and then in their separate coops(with the same fencing) that were built side by side for 2 1/2 months. I've got 12 baby chicks that I picked up today from the post office. More are to be delivered on the 26th of this month. Since I've always had standards I wasn't sure if there was something else I should be doing to help facilitate a non-threatening introduction when that time comes. I was just thinking and wondering if the chickens really know if there is a size difference.
