I houhouse lots of different "bantam sized"/small breeds with the Silkies girls.Interesting pic, thanks for sharing. That's a great illustration of why crested breeds can be more fragile than regular birds. I think it depends quite a lot on the situation. Generally speaking, I agree that Silkies ought to be kept away from confrontational or aggressive breeds and generally anything much bigger than they are. But I don't find there to be anything wrong with keeping them with smaller or similar sized, non-aggressive breeds of bantam. I've seen innumerable situations where this worked just fine - my own flock included. This occurrence with Carlos and Midwest had been the only aggression incident to occur between the Silkies and other breeds in the bantam pen over the past 2-3 years of housing them together. Granted now that I am going to be working largely with Silkies and since I want to add some more aggressive breeds to my bantam pen for the sake of variety, I'm drawing up designs for an additional bantam pen to house the Silkies and Booted Bantams (also a very gentle breed) separately. But in the case of a small flock, I personally have seen little issue when housing limited numbers of Silkies and mixed bantam breeds in the same coop and run, cocks and cockerels included. The biggest problem I've had is the roosting fowl pooping all over the poor Silkies at night.I raise a few different breeds of bantams as well and I know not to even mix them beyond in the brooders. The crested breeds like my silkies and polish especially don't do well with other breeds. The huge beards and crests impede vision. The silkies can't fly like other breeds and have no way to get away from an attacker. When you get into stock with smaller crests and beards, then they might do ok. Silkies and polish often have vaulted skulls too and skull plates don't fully fuse and leave the brain exposed with just skin covering it. As you can see from pic below, it will show you why those breeds can be so delicate.![]()
