RIR vs. Cochin Rooster?

[slimpys]

We have 13 chickens that we raised since they were chicks. 2 turned out to be roosters - the RIR and the black Cochin. Which rooster should we keep for a mixed breed flock? They are only between 4 - 5 months old and both have been moderately friendly. Is one breed better/worse to have as the rooster? Any traits I should look for to help me pick? Thanks!

As a generalization, cochins seem to be less aggressive than RIR. If at all possible, I would recommend keeping them until they are more mature so that their adult personalitites develop.
