I have 3 Silver Laced Wyandottes and last week a Thai gamehen showed up. She hung around outside the chicken fence, obviously looking for a home. After a week, I had her vetted; no lice, mites or intestinal parasites, so she was invited in with the others. We've had the usual pecking order squabbles and they won't let her into the coop, but that's as expected. But today while I was hanging out in the run, the newcomer started a very odd thing - she ran at the other hens full face on and tucked herself down and ran UNDER them, one at a time. She did it to all of them for several minutes. The Wyandottes were totally confused. Is this some sort of submission ritual?
