ORChick-
I'm betting you WILL find your hens relaxing. Ours certainly have proved to be. Even my DH, who was pretty much just along for the ride when my daughter and I said we wanted chicken, loves to go out and watch them when he gets home from work.
Like you, I used the planning stage (which for us was quite long since we had a 4-month battle with the city to be able to have them!) as a sort of therapy, too. It was pretty fun. I found several sites on line which gave chickens egg-laying and personality traits and my daughter and I narrowed down out list from there (cold-hardy and winter laying were also on our list of criteria since we live in Maine.) WE ended up with 5 girls (the feed store forgot our buff orpington!) and I'll let you know what they are like below. I have noticed that breed traits are NOT consistent, ie someone else's red sex link might be mean, or whatever...
1 red sex-link (red star, cinnamon queen, etc)- she is smaller than the others and started laying the earliest, at 20 weeks. She was a bit stand-offish as a chick but now very friendly; she'll jump up on our laps looking for treats and tolerates being held very well. She's pretty quiet. I expect she'll be our best layer as they apparently never go broody and lay well all winter. She's a bit hyper.
1 barred rock (plymouth rock) She's always been very sweet and friendly. kinda mouthy when she wants attention (ie treats!). I believe we just got our first egg from her this morning (21 weeks). She's very laid back, we call her the Zen Hen.
1 black australorp She's been the most outgoing from the start, trying to eat EVERYTHING (ate my daughters pearl earring as a chick!). She was really scruffy looking and homely as a young pullet but is now drop dead GORGEOUS with irredescent black feathers, super soft, and these beautiful deep auburn eyes. Very freindly, quiet (she has a cute squeaky little voice when we hold her) and outgoing. Not yet laying at 21 weeks.
1 Rhode Island REd The loner. Friendly to us but always on the fringe of the group. Recently risen to lead hen and MEAN to the others, although I hope this is just a hormonal start-to-lay thing. First egg yesterday at 21 weeks.
1 Silver Laced Wyandotte Very laid back, almost stupid. Sits down a lot, or hangs out on the roost while the other girls are busy-busy-busy. Very quiet. Freindly, easygoing, but not outgoing. Not laying yet at 21 weeks. Gorgeous feathers!!!
I hope that helps. Have fun!
