I recently got my ladies 10 RIR and 1 Ameraucana. All came from the same farm but completely different pens(RIR in one and Amer. in another) And they definitely have the gang/mob mentality. I only have one run and coop Run=10x8 and coop 10x9.5. At night i let them be together and all is wel during the day The 10 gang up the poor Amer. Right now i rotate them every hour or so between the coop and run(food in coop and water is in the run) and for 2 hours of the day I put the Amer. inside a dog cage inside the coop when I open the pop door for them to do as they please. Should I Put the 8 younger RIR in the dog cage instead( they are the main offenders) And let the older 27week RIRs be with the Ameraucana? Any help PLEASE. I know they are going to establish a pecking order, but the poor girl doesnt get a break with out me doing as I am?!.
