I know this thread is sort of old but I did have an interesting experience tonight. Well, Jagger will sit and lay on my shoulder if I put her up there, but she'd never sit in my lap or go up on my shoulder by herself voluntarily, even if I put the rest of the chickens in the indoor part of the coop and it's just the two of us.
However, tonight I was able to lock up our cats and take Jagger inside with a cat carrier (and then holding her at our computer desk) tonight to show to family on Skype (although really it was an excuse to bring my girl inside!). At first I held her nice and good in fear she'd freak out and run amok, but she stayed on my lap the entire time I was sitting down. Was it because she was in a new environment and I was the only familiar sight? She panted briefly once or twice, but she mostly seemed intrigued by the house and didn't seem afraid when me and my little sister stroked her feathers, something she usually would run away from, and she just sat there cocking her head on my lap, completely chill for the most part, while my brothers played pool loudly right next to us.
Thoughts? Jags will be 14 weeks old on Tuesday.
