First time chicken owner wondering gender of 2 chickens

[kb105059]

Hello All!
I got 6 baby chicks on Friday June 10th 2016. They were only a few days old when I got them. So now they are about 20 weeks old. I have a Rhode Island Red and a Buff Orpington that I am questioning if they are a rooster or not. The Rhode Island Red I am questionings name is Mark and his sister is Margo(I have put pictures of both on here). And the Buff Orpington I am questionings name is Peaches, and his/her sisters name is Wilma(I have put pictures of both on here also). Please let me know what you all think. I appreciate your help!!

Welcome to BYC.
Looks like pullets to me. Mark & Peaches look to be close to laying their first eggs.

Oh good. Just what I wanted to hear. Thank you so much for your quick response!

All pullets. Mark will probably be the first to lay.

Everyone looks female. Mark will be giving you eggs literally any day now

Where did you get the chicks? Peaches looks female, but not like an Orpington at all. Too lean and upright.....

I agree with everyone else, all look to be pullets and Mark looks close to laying!

Where did you get the chicks? Peaches looks female, but not like an Orpington at all. Too lean and upright.....

I agree on Peaches.....and is it me, or are her legs grayish colored? Could just be the pic though. She looks a wee bit Sex-Linky to me, but if her legs are gray she could also have some EE.

all pullets. agree Peaches doesn't look like a buff orp

Pullets.

Peaches looks like a very hatchery quality Orp to me. Which is to say a generally golden colored mutt, like almost every other hatchery Buff Orp. It's Leghorn outcrossing to improve egg production, I'm sure.

Sorry to "butt in" but how can you tell that Mark is ready to lay?
