The welsummer on the right on the top picture and on the left in the bottom are definitely roos. Not sure if they are the same chicken? But just check for black feathers on the chest. Hens don't get black feathers, their chests will be a nice salmon colour all over!
Thankyou.
Not the reply I wanted, but it's what I feared.
Now I need to find a similar aged Legbar girl, and work out what to do with my 3 beautiful boys.
