I recently found out one of my chickens is a rooster which I will have to get rid of. That leaves me to only one pullet that is 14-15 weeks old. Will she do OK in a old flock of two old hens? I put all of them together even the Roo last weekend and they seem to be doing ok. The old hens just bully and exclude the other 2. I will be getting rid of the Roo soon. Will my pullet be ok by herself? Or should I wait a couple more weeks before I find the Roo a new home?
