I agree with the sexes. I am not familiar with the swedish isbar, so can't comment. I don't know/remember where you got the chicks from. Do they have Welbars? If so, Cinnamon may well be that. If they have Bielefelder chickens, I believe Pecan could be that. Both I'm going on pictures of them people have posted in a thread I'm on, not personal experience.
Also, one tiny caution. Peanut seems to be a bit behind the others feathering out & filling out.
Sometimes late developing ones seem like hens until later when all of a sudden, nope, they are Roos. So, while atm Peanut appears to be a 'she', keep an eye on her over the next couple of weeks to be sure she
'remains' a 'she' and doesn't '
become' 'he'. I had one of those. My sister was over and I suddenly said 'Oh, no, you can't have become a boy!"

My sister, insightful person that she is, said " Um, he didn't just become a boy"


No kidding, but I
was sure that he was a she until just now!

His comb & wattles pinked practically overnight - and almost a month behind the other Roos!
