Hi guys I'm new to raising chickens and after much research I'm stumped on exactly what breeds of chickens I have and some whether what sex they are I started our with just a few but acquired some here and some there and now have 2 roosters for sure and the rest girls I hope. So yeah any help determining the sex and breed is much appreciated. I bought some Road Island Reds and so far they look like the pictures I see online but there are a few that are a bit brighter:
I bought a few at a different feed store that told me that they ONLY had RIR but when I got there these (in my limited experience clearly were not) were the only ones they had and looked nice so I bought them:
The two lighter ones are the ones in question I think they are Orpingtons.
When I was at the same store I bought this one too because it looked cool but what breed is it?
A friend of a friend gave me four chickens and I know one for sure is a RIR but the other three I have no idea what breed or even there sex all are extremely flighty and seclude themselves from the rest of my flock which range from 5-7 weeks old about the age i assume these are also:
this one is missing its tail feathers I don't know how it lost them
This one ran out of my dog kennel that I used to transport them and squared right up with my young rooster and they both flared out their neck feathers so that makes me believe its not a female.
This one I have no idea on ether
Thank you for the help guys.
