Yes. All mine do that - like putting themselves to rights after 'an unfortunate encounter'.I've got a question. If you pick up one of your hens; she needs to be of egg laying age, when you put her down does she shake herself as if adjusting her feathers?
And my cats all lick themselves after I touch them - like they are ridding themselves of my scent even if they initiated contact.
Hurtful in a way, but I am resigned - I pay for the food, I get cuddles if I want them and everyone just has to accept that deal.
