My RIRs will be 3 wks. old Monday. When we first got them they didn't mind being held. Well that isn't the case anymore. They run to the other side of the cage when they see our hand coming near them. They chirp,shriek and flap their wings. I've tried hand feeding. I thought maybe they would associate my hands with getting fed. Which after they figure out I have food in my hand they do eat from it. They've even hopped into my hand but as they get bigger so does their beaks. Peaking is getting painful. They like to listen to us talk. They crane their heads up to find our voices they just don't liked to be touched. Is this normal?
