By choosing the only snuggliest and least skittish of personalities, would one be able to eventually create a consistently friendly chicken? (with even consistently friendly roosters?) Would I have to worry about killing their survival instincts? Or could I get them to be friendly with humans but wary of predators?
I have had some Old English Game Bantams that were the first to fly into the trees if a dog chased them, but they were also among the first to come be friendly with people, or to investigate a new "scary" thing (bedding, food, rake, etc.) If I picked them up, they tended to be calm, rather than struggling and sqawking like some other chickens did.
So based on my experience, yes it might be possible to get some chickens with all the traits you want.
I got the Old English Game Bantams from Ideal Poultry. I do not know whether ones from other hatcheries would have different temperaments. I had one each of several different colors. Only some of them were noticeably friendly, but I couldn't tell whether there was any link between color and behavior, or if it was just random among the ones I got.
i'm wondering if could I create a super friendly chicken breed? (i'm aware there already are friendly chicken breeds, but i'm thinking about friendly chickens that produce consistently friendly offspring. Also, i'm not just thinking about chickens that are simply docile enough to manage, but chickens that are personable and would love to be around people.)
You might start by getting chicks of quite a few breeds and paying attention as they grow up, to see what traits you like or don't like.
Here are a number of differences I have seen in chickens:
--Does the chicken approach the person who usually takes care of it?
--Does the chicken approach a strange person?
--How does the chicken react to an unfamiliar object? (rake, pile of bedding, piece of cabbage, etc.) Some are more scared than others, and some settle down and investigate faster than others.
--When you pick up the chicken, is it calm or does it struggle and squawk? This may be different if you corner it and grab during the daytime, vs. grabbing off the roost at night.
--How quickly does the chicken get used to things? (Much calmer the 10th time you pick it up, decides the lawn mower is fine after the first month of summer, runs to eat every new food you throw in, vs. still freaking out every time.)
Those differences do not always go together in predictable sets. I have seen them mixed and matched in many combinations.
Personally, I like chickens that are calm when handled, don't panic too much about new objects, and rapidly learn which things are safe to eat or non-threatening. Your top priorities might be very different than mine.
If I was to go about it, would it be best to not socialize them as much as chicks, and wait to see which ones are naturally friendly, without any training, or would I try to make them as friendly as possible and just choose the friendliest ones?
You could do it either way. You will just get different results.
I have noticed: if I pick up a chick once every two weeks (maybe to check whether they need a larger legband), some will struggle frantically and peep loudly while some will not. When I tracked this with some chicks (made notes each time), there were some consistent patterns. Certain ones always struggled, certain ones were always calm, certain ones struggled the first few times but improved with time (they learned or got used to it).
If I were also to strive for a certain feather color or another external feature like that, would I work on it before I try to encourage the friendliness, after I’ve already got a lot of freindly ones, or just during the process?
The more traits you try to work on, the less progress you are likely to make on each one. But it would not be hard to get some basic points consistent.
For the basic color, you could just start with that color. For example, if you want buff, you could start with birds of several buff breeds and breed from the friendliest of each. Or you could work with just black. Or whatever other color you like.
You could also start with feathered legs or clean legs, crests or no crests, blue eggs or brown eggs, or whatever other traits interest you.
If all the chickens in your flock are consistent for a certain trait, then usually the offspring will have that trait too, without you having to pay any special attention to it (of course there are some exceptions: traits that never breed true, or recessive genes that pop up in later generations.)
