They are very dear birds, I agree.
While I am 95% sure that they are all girls at this age, silkies can fool you.
What color are your boys?

I thought maybe my Splash had streamers? My boys are 2 - black, gray & white. They are all much larger than these 4. I can grab pics

Here they are! I had to show you the white roos chest. I’ve never seen one so big. He reminds me of a buff cartoon hero Him and the gray are hatch mates. The blacks are the same age as the other 4 hens (hopefully) I posted up above.

All very handsome boys! Love the white one, though all appear to be nice examples of the breed.
My boys are bigger than the girls, too. The difference starts to be noticable around 3 months of age, usually.
That's quite a difference in yours though!

Well @LadiesAndJane was correct! I have four ladies and four roosters. Question for those who understand genetics: Which of my roosters should I keep to have the most color variations of chicks?
