Am feeling very guilty now after reading all your comments about lone and lonely chickens.
Mindy Araucana lives by herself - her coop mate and friend Moppit Silkie died, and when I tried to integrate her with my remaining birds, my Welsummer tried to literally kill her. Tried it a couple of times, with the same result so there was only one solution. She roosts at night with a toy dog as a companion ( which she turfs onto the floor every now and again ). The two big girls accepted friend Milly Barnevelder, up and died, hence I have now only 3. ( they were all purchased at the same time from the same breeder ).
They all get together at the double separating fence ( had to do that too, as Mandy Welsummer would try to grab her through a single wire fence ) .... and have some kind of conference every evening. Always the 3 of them standing as near as they can get to one another. I'd rather have a happy healthy and non-injured ( or worse ) bird, than try it all again.
So she has bachelorette quarters. If when free ranging she goes anywhere near a single fence, Mandy rushes over to try and peck at her. But Mindy is a wake up to all that now and gives the fence a very wide berth.
Have thought of getting a few more ( 3 ? ) Araucanas, young ones, and seeing how they go with Mindy, but if it all goes pear shaped, it means we have to make a 3rd run and new coop. Simply cannot cope with the thought at the moment.
So - I stand convicted .... I have a lone chicken. !!
