I think I have some Australorps

I got some hens from a friend who had too many and they are supposed to be Australorps (sp?)
They were rescued and were in a cage all together. They lay snuggled together like little chicks. They seem to think they are still in a cage. I have a very large, fenced in area for them to pasture upon and they are new to the grass, too. They are very sweet but shy and I have to block my older hens from bothering them when they eat. Any ideas of gender or breed would be helpful.

Thank you in advance.

 

Thank you so much.
