There are some excellent articles and threads here regarding socializing chicks - I would suggest reading through them to get some ideas as to how to build a friendly relationship with your flock.
I will say we have BO, GLW, SLW (the three you mention) - as well as Easter Eggers and Light Brahmas right now. The BO are all three VERY friendly, always the first to greet you, jump on your lap, etc, the 3 EE turned out to be two pullets/one cockerel - one pullet is almost as friendly as the BOs, one is an absolute nut but starting to settle a bit and the cockerel is not friendly, but that is okay with me as long as he does not become aggressive. The SLW and GLW are all curious, but standoffish - though beginning to settle a bit more as they reach the point of lay. The Brahmas are attention hogs - more out of a desire to have what others have than to actually receive our attention (if the EE or BO's are on my lap, a brahma will try to shove her way in and push the other bird/s off, etc). All 16 of these birds have been raised together and in exactly the same way - and all have developed their own personalities, while breeds can offer up general guides as to what a particular type of bird may/may not be like it really boils down to the individual.
