Thanks again everyone
A few things worth mentioning:
I decided Not to separate her from the rest of the chickens, if they had been picking at her I would have, but as it is I think it would cause more stress then anything and besides, I really dont have anywhere to put her.
They all went in for the night a little while ago and things are definitely off.
Hazel and Domineak are both in their regular spots on the roost.
The australorps always sit on the beam that crosses where the Dominiques sit, on the south side.
Tonight the Australorps are sitting on the north side; none of the chickens have ever sat there before.
Domineak seems a little restless as well.
The two younger chicks were in the extended run all day.
Hazel spent her "outside time" watching them, while the others ate and had dust baths.
I'll be keeping an eye on them all night... as I always do
Morning should tell.
Thought someone might find that interesting.
