I have a hen and a roo, sebrights,: she is laying, also i have a few RIR (they are alittle younger) the sebrights seem to be real aggressive with the RIR, are they a mean breed, also i have a male and female mallard duck full grown, would it be safe to leave them with the chickens, i am needing some advice as we are not the brightest egg in the batch, thanks, mike
