My bantams have the most personality. They are such sweet and fun birds. They are my favorite.
Our Silkies were personable, sweet, fun birds and our favorite. By the time they reached full adulthood by age two they turned into grouchy, peckish, flock political birds as any other LF breed - still sweet but definitely flock-assertive.
The thing we had to change was the size and temperament of the LF because a 2.5-lb Silkie doesn't stand a chance in flock politics against 6-lb+ heavy LF. Everything is balanced in our flock now temperament and size-wise with no LF over 5-lb and gentle natured. We have no breeds like Marans, RIRs, SLWs, Orps, Lorps, BRs, etc. that grow too large/heavy and bully smaller breeds in the flock. Even gentle heavy breeds like Sussex or Brahmas can be tempted to bully smaller fowl. Many Mediterranean class of fowl are lightweight but can become aggressive toward bantam-size birds. As pullets the heavy LF breeds can be as sweet as pie in a mixed flock but at full maturity over 18 months old they can become domineering, cruel, vicious, or just plain unpleasant toward smaller or weaker breeds.
Since APA Ameraucanas are friendly, non-broody, mostly non-political flock birds they were a good choice to mingle with Silkies. In fact, Ameraucanas are so friendly I wouldn't stress them by putting them in a heavy LF flock either.
We are adding two 4-lb gentle non-broody Breda pullets to the flock to try around the Silkies and Ameraucana. A breeder friend said it was a good addition for the temperament of our flock so we're looking forward to them.
