From the one side profile of your olive egger in that last picture, the tail feathers look to be curving and possibly pointed... which could mean Roo
but it doesn't have a very big comb...
Thats tricky my black Olive Egger roo had a very noticeable red comb at that age...
It's just that last picture that gives me rooster vibes... anyone else think so??
that’s how I’ve been feeling! Recently it seems like the tail feathers are starting to arch out!
Ill post better pictures of both for you @homeschoolin momma
Ok, I'm still going to say pullet for your OE. Her comb is a little red, but not big at all. I am however going to lean towards cockerel for your silkie. I see a tinge of red at the base of his comb and it's a decent size for his age. But every chicken is different in its quickness of growth and silkies are HARD.
Saddle feathers for your OE will start coming in in about two to three weeks. Pointy ones will tell the tale on if we are correct. Streamers will start to show on your silkies head if a boy, although they are harder to see sometimes.
