Ashley, it sounds as if you are having a wonderful time immersing yourself in the world of chickens!
OT for BYC, but had to share - I thought the same thing about trees when I first moved to CO from upstate NY, but having struggled to grow trees for the last 15 years in three different homes, I can tell you, they take a lot of extra work here. This year in particular has been very challenging, between drought and hot, windy days. I have trees that have been in the ground six years that I used to be able to water maybe once a week, that I have had to water every night this year. I let an Aspen go two days, when it was 100+ and windy, and it looked like someone took a torch to it. Luckily it recovered. Over the last 6 years we've been on 42 acres just south of Pueblo where we have planted hundred of trees, and lost dozens - lost three Lombardy Poplars to gophers over two winters. We have developed a planting technique that is a huge pain in the neck, but it works. We did the hole, then line it with a double layer of the small-space chicken wire molded into the hole, like a basket. Gophers can still chew some of the roots, but they can't get enough to actually kill the trees, just slow growth. Last year, Bob trapped (as in, kill trap) 23 gophers, this year we're up to 8 so far. About the time the trees look really great, one of the following occurs:
1 - MAJOR hail storm strips them all bare, about 80% recover
2 - Antelope come by and bite off all the new branches - not to eat, they leave them lying on the ground around the tree; now have water-shooting scarecrows around their favorite targets
3 - Young buck antelope scrape all the bark off with their horns (just happened again to a Maple and three Locust - with thorns!)
4 - rabbits girdle the trees - chew a circle all the way around the trunk which kills the tree (and they are too cute to kill, so now we feed them to keep them away from the trees - sounds crazy, but it has worked for 5 years)
5 - Borers attack the only two big trees we have, Cottonwoods, which grow fast if you water them; $100 worth of borer treatment later, one is essentially recovered, the other is still iffy
Trees that were weeds in NY - Sumacs - we now plant on purpose because they will usually survive, recover from having every leaf removed by Antelope, and grow - slowly, but they grow.
Anyway, back on topic - right now I have one Blue Cochin, and she is an absolute delight. She still isn't exactly fond of being picked up and held, but it doesn't matter, she is the funniest, silliest hen, and I adore her, I don't blame you one bit for preferring them, and there's nothing wrong with that. The others will still do what you selected them for. The Cochins you selected because you just like them - so they are fulfilling their purpose as well.
Best of luck to you.
