Does the adding to the flock go basically the same for ducks? We have had our current crew for a little over a year now and finally had an intruder, (big coon) he has wiped out 1/2 our hens and he got our male duck! We are getting more hens, aprox the same age as ours but want to get a few ducks for our lone girl. Will she be the odd man out even tho she is in her home space? We have gotton rid of the coon and did some tweaking to the run,so hopefully all is well now.
She'll probably have the upper hand being on her home turf. You could try getting 3 new ducks and introducing 1 (the male or calmest female). They can bond and will be evenly matched for any squabbling. Then you can introduce the last 2.
To the OP:
If you have a particularly laid back hen in your flock, perhaps the lowest in the pecking order, you can do something similar. Put the new silkie together with the hen, let them bond, and then release them back into the flock. The original hen will have to re-establish herself in the pecking order along with the silkie so they'll be picking on both of them. I have learned from experience that establishing pecking order while chicks can go almost unnoticed but add a couple younger and smaller chickens and it can get brutal.
