First of all, I am getting ready to order some silkies and since I can't order a hen specifically (I have to order SR), do you think 4 is enough to get me at least 1 hen? Next, I have 20 mature large-breed birds right now and am raising 19 chicks with more on the way. They're in a pretty large outdoor fenced in area and are let out to free range in the afternoon. I always keep my chicks separate of course until they're "of size" to introduce them to the rest. However, with the silkies being smaller, will they be able to find their place in the group okay?
