More chicks at last

After searching long and hard, we finally acquired some more chooks. We got these little girls from Chesterfield Farm, and they were only 12 weeks old (that was a week and a half ago) so it will be a couple of months before we get any eggs from them.
The two spotty ones (centre) are Mum's, and she has named them Flora and Dora. The grey one (back) belongs to our neighbour (a bit of a joke) and Mum tells me its name is Cora, but I don't believe here. The two black ones are mine, and they are as yet unnamed. Any suggestions? One has a few brown feathers around her neck (it's hard to tell, but I think it's the one on the left)
