Pick 1 male for your breeding goals.
If you want to breed both std's and silkies, they'll need to be separated anyway,
so best to keep them as separate flocks with 1 male per flock.
Yes, it's one of the hardest things about keeping chickens.
If you are going to be hatching, you'll have to come to terms with it in a way you can get comfortable with.
PSA FYI:
The 'rooster' to hen ratio of 1:10 that is often cited is primarily for fertility efficiency in commercial breeding facilities.
It doesn't mean that if a cockbird has 10 hens that he won't abuse or over mate them.
Many breeders keep pairs, trios, quads, etc....short term and/or long term.
It all depends on the temperaments of the cock and hens and sometimes housing provided.
Backyard flocks can achieve good fertility with a larger ratio.
