The other photos aren't that clear, but with this one I can see a bit more.
Yes, I agree, they do look a bit bloody. Pin feathers will bleed if picked.

You may find that the Silkies are getting plucked by the large fowl. Sometimes it's a space issue. Some folks have found that their Large Fowl just don't get on well with Silkies. Observe and see what's happening so you can make some corrections.

You may need to separate them at night then.
