Math Ace- sorry it took so long here, I have had major computer problems over that last week or so
It is really hard to tell anything on your birds except the coloring and tails on the pullets- if you can take some time - and they are so active, it will take time, see if you can get a profile shot, a straight on front shot, and then a rear end shot and a shot from straight down of each bird, it will be easier to tell what you have. At this point, all I can say is that the first two pullets are way too light- you would need a very dark roo to offset that, from what I have come to understand from old breeders. Also, the tails look pinched- when you look at them from the back, they should look like a very open triangle. The picture of the last pullet looks like she has some color- the roo is very hard to tell anything on in that picture- his tail does not seem to be there yet, , but watch for it to be barred black and white. If he has yellow legs, that is great! Again, better pictures will help us all to help you more with this.
And I love that last pullet- she has a pretty, pretty face and looks like she is plump. You may be able to work with them, depending on how the roo really looks. I am a believer in "Start where you are with what you have" if you can, and in another month or so, you will be able to tell more on the roo especially.
