@Onebroodymomma - Maybe they were mistreated at their old place? How long have you had them? Maybe it'll just take time for them to trust you.
General - I've had 6 of mine since they were baby chicks and it took ~8 months before i was able to *sometimes* pet them. They'll follow me around and huddle near my legs, but they aren't fans of snuggling. I personally, would never kill a chicken because I wasn't getting enough snuggling from them. But that's just me.
That is a rather hyperbolic interpretation of what has been said above regarding culling. Not everyone views their birds as purely pets- and there is not a thing wrong with offering a humane end and making use of birds that are culled for any reason the person in possession of them sees fit.
