this is my second year raising chicken. Last year I started with four (2 Barred Rocks, 2 Rhode Island Reds). I lost one of the Barred Rocks I suspect to the neighbors dog but never found it so my wife likes to think it went wild! This year we decided to expand, we bought two Light Brahmas one of which turned out to be a roo and became dinner. We also got 2 ducks, and 6 more chicks from a local breeder. The 6 chicks are of questionable breed but I think one is a Dominique hen ( very large same coloring as the barred rock) Three of the other chicks turned out to be what I believe are orphington Roos and the last 2 look like Easter egger hens. Anyway I don't plan on breeding at this time so I plan on processing the two remaining Roos as the neighbors dog killed the third. My problem is that the huge hen which I believe is a Dominique won't stop harassing the smaller hens even the Roos which she is also bigger than. It has gotten to the point that one of the hens keeps jumping the fence each day and coming back each night and it's only a matter of time before the neighbors dog gets it too. The other two hens (Easter an brahma) along with the two Roos only leave the coop to get food or water and when they do leave the Dominique often chases them until the run back into the coop and I worry they are not getting enough food and water. So the question is, Is it a matter of size because she is so much bigger? Will they eventually work things out or should she become dinner along with the two Roos? I like the large eggs she has started laying but as things are now either she will have to go or the other two will ( she leaves the 3 original girls alone as well as the ducks) I've heard the cost vs gain is bad with Dominiques as they eat a ton but I am inexperienced with different breeds an I'm debating whether I should get rid of her or the two smaller hens which so far lay small eggs.. Next year I plan to increase the laying flock as well as getting 15-20CX birds for meat so I'm trying to keep in mind how they will do with the existing birds so any advice would be appreciated.
