Exactly what we were thinking.
Put the mean one out with the nice big hens. They will teach it to be civil.
It will learn that it is not the big mean one after all...
These birds are feathered and ready to go out, weather permitting.
We seperate all the time, usually in groups, the older babies go into another indoor brooder for this reason, and they do get obnoxous and can injure the smaller ones because of their size difference.
Then, we send them out to the outdoor brooder. There they have a new world to deal with.
It is the next step for normal chicks.
Where they become used to the larger birds being around.
It is the natural order of things..
In this case, where one is a bully, I would hasten it's studies, if you will....
And, send it out into the outdoor brooder, or hen house ahead of the other "babies" to learn the value of being part of a flock.
I would check on it all day though, in case it needs help. Finding itself in a flock and being small will scare it.
And that is not the message we wish to send.
Once it learns that it is not big.... hopefully it can be returned to the group.
