Hi everyone. I'm new here and to chicken raising. I have four 13-week Black Australorp pullets and eight 11-week straight runs of which four are Dominiques and four are a mystery. Of the latter, one is all white (was a pure yellow chick) and three are reddish brown. I don't know if they are EEs, RIRs, Production Reds, ??? Two act assertive and have well developed combs and wattles. One is clearly a hen. As for the Dominiques, three are lighter and have varied size combs (the one with the least crowed first) and one is darker with no comb and acts like a hen. So I am guessing I got 5 roosters out of the 8 straight run chicks. Here's my question--which rooster to keep? They alternate picking fights--the largest red one was great until I got three new barred-rock hens (fully grown) and he tried to kill them through a wire barrier I erected. Someone told me never to keep red roosters as they grow too aggressive but I've also read that Dominique roosters are often very mean. Any advice much appreciated if you can identify the red ones and/or have ideas on which rooster to keep (the other four will go to someone who will finish raising and sell them).
Here is the first mystery red who I think is a cock:




Here is the second mystery red who acts very much like a cock:



This is the third 'red' chicken; I think she is a hen:

And this first photo is the only Dominique I think is a hen--the others (two of three are in second photo) are lighter and have combs coming (plus at least one has crowed):

Finally, this is the all-white one who came with the reds. Will she (assume it's a hen) lay white eggs?

Can anyone confirm my suspicions and/or advise about roosters?
Thanks very much!! Love this forum--have been reading nonstop---
