The thing is no one has problems mixing the species until they have a dead chicken. Mine are heritage too. They are very active birds. One peck to your silkies skull could be enough to kill it.Wow....so much to take in. If I had known all this, I probably wouldn't have included a Silkie in the group. Others on a thread I started in the turkey section of this forum didn't mention the potential dangers.
The turkey varieties we bought are heritage, the mature size of which, thankfully, won't be significantly as "huge" as that of the BB. Unfortunately, though, we don't have a separate setup for them. All our birds free-range and cohabit together.However, do you suggest that once Schnitzel is old enough to thrive without artificial heat, I put it in with my 4-week-old chicks to prevent further bonding with the poults?

I'm not saying my turkeys walk around murdering chickens, but it's always a possibility especially when birds are kept together 24/7 and the chickens can't get away. I personally wouldn't keep silkies with other large breeds of chickens either. Silkies are a bit odd and they can get in trouble because of their behaviors and inability to see well.
I'm a bit too cautious at times, but I unfortunately learned many of my lessons the hard way. I can only recommend stuff based on my experiences, and mistakes.
It may help to get the silkie away from the poults and let the poults mature away from the chickens, but you can only do what you are set up for. If you ever see any aggression out of those turkeys towards your chickens be ready to separate them out.
