Hello,
If you do have more than one rooster, if one is a Welsummer, the other should be another Welsummer or one of a large breed.
I had one each of Welsummer and Australorp roos who fought all the time. anything smaller than the Australorp would be injured or killed by a Wellsummer who will be a larger bird. My two finally came to a detant but the Australorp still was in a fightin' mood if the Australorp tried to mate a hen.
Further, the hens began to look worn out with feathers missing on their backs and where the roos grabbed onto their necks. I thought two roos for the 20 hens was too many and kept the Australorp and sent the Welsummer to freezer camp. The flock seems much more calm and the hens appear less worn (except for the two or three favorite hens--or at least the slower ones who do not often avoid the roo).
'just one man's opinion.
