I'm a first-time chicken-mom and have two different batches of chickies. 6 RIRs I got from
TSC from the day they arrived and have been handling them since (whether they liked it or not). Most of them are pretty tame (although i do think i've got two roos in the mix and they're less 'friendly'). It's gotten so I can stick my hand/arm into their hutch and they'll take turns jumping onto my figers/hand and just perch there. Sometimes I'll take them out and hold them (they then like to fly all over the living room and it's a dash to get them before the cats figure they're out!) But they're VERY friendly, always wanting to know what we're up to, where we are etc.
Then we have the newer batch. Some had been handled, others not so much. So I just take my time holding every one of them. They DO like to see their buddies when I'm handling them (otherwise the screaching chirpping starts up). If they seem to be 'freaking out', I at least hold them until they've calmed down and start to doze off, then open the door to their hutch and give them the chance to hop/fly off. (Sometimes they do, sometimes they don't).
Food treats don't work as a good/consistent bribe with either group but they do know I WILL feed them, give them fresh bedding etc. We (hubby, daughter and I) also greet them daily and talk with them daily. So when I say "good morning ladies", the RIRs all jump on their perch and start 'chatting' with me!
Don't lose hope, I do have a blue orpington, and s/he is skittish with me as well. I just keep on keeping on with the holding and petting. Speak softly and gently, and be persistant.
Good luck and let us know how it goes.
