I got my first chickens on Sunday from a swap, a 9 week old RIR and a 6 week old silver laced wyandotte. The only thing I couldnt find while there was an EE. I managed to find a 7 week old EE Monday and picked her up that morning. Everything seemed to be going well until Tuesday when I started to let them out in the run. The RIR has been relentlessly chasing the EE, the poor girl is so frightened she hides under the coop most of the day. The RIR is 100% fine with the wyandotte who almosy seems to look to her as mother hen; and I should mention the three of them sleep together at night. My question is how long should I wait before saying "this isnt working" and finding an alternate solution (which would likely involve finding a new home for the RIR and getting a younger one)?
