Hi, welcome to BYC!
And congrats on your new SFH!
I haven't heard of being able to feather sex them, so I am not sure. But the ones I had with short tails compared to everyone else have always been male. But not all males have those short tails. And most of mine with 2 exceptions, I was able to tell by combs and waddles by about 6 weeks although 2 were late blooming cockerels.
Yes, it's always fun to see how chicks turn out. Out of the 8 I have, some may look similar but not a single one is the same!
Where are you at in Oregon? I'm just south of the border in CA on the coast. I hope you didn't get them from people in Gold Beach claiming 100% organic! Those people are scammers selling mutt birds for a HIGH price....
Hope you love the SFH as much as I do. Right now I have a lap cockerel, usually hang out for a good 20 minutes. Sometimes even napping!
