#identifying

Hi, I bought some chickens a month ago (I'm new). Loved them and bought more. Now the one in question is the orange-gold one with the uppy stance who was supposed to be a RIR cross Sussex pullet. However I started to question that because she looked so different to my other RIR sussex pullets...

I have a Rooster which I Believe is a Plymouth Barred Rock and an almost pure white Dalaware hen with a black color on the tail feathers(however the are no visible black sports on the bird's neck) what are the offspringso called? [The offspring was what looked like buffs,with the black spots...

I got 3 americaunas, none look like an americauna, but this one looks way different than the others! Can someone please help me figure out what chick it is? I am so stumped. I’ve never seen on with markings like this on the face. It’s got eyeliner, zig-zags, and it’s super fluffy.

I need help identifying the dark colored duckling on the left! It is about four weeks old and at first I thought she might be a blue Swedish but as she's getting older I'm not sure! Does anyone have any thoughts??
