Questions about Bluebells and Black Rocks?

[bops]

What sized hens do they grow to be? What do they lay like? Are they okay around people? Do you have either?
I bought one of each today Without a clue about either breed haha, I did notice the Black Rock looks very close to my Barneldver though, Which I like

I have a black rock shes not at all aggressive but she can be quite shy she will happily follow me around the garden but does not want to be touched this might be because I bought her at point of lay instead of as a chick , how old is yours ?.shes is an excellent layer giving an egg almost every day ,her eggs are a light creamy brown colour and black rocks are a hardy breed so they are good for cold weather.
