after the rooster is done the hens shake their feathers and look unsettled.
This "shaking of the feathers" after a breeding is a necessary part of the breeding. When the hen does that, she is "shaking" the sperm to get it into the "storage area" in her reproductive system. This "sperm storage" is the reason why a hen can remain fertile for 2 weeks or longer after a single breeding. It's easy for us humans to interpret this behavior as the hen being "unsettled", but that is far from the case! Usually, the hen, after the shaking ritual will continue on with what ever she was doing as though the roo had never even been there! And, often, she will follow him around for a bit after he breeds her.
