all i can say is keep offering treats from your hands they will eventually come to you!!!! you are totaly right chaseing them around the cage isnt going to help it will stress them out.... i wouldn't advise a HUGE cage i have a 3 tier cage that has several doors wer i can reach. also has been amended so i can close off parts of his cage to make it easyer to catch him. this can be done by placing a book of something over the top of the ramp.. as for the chin tickeling then yes its just a stage she is in she will get back into the habit of wanting a fuss.. but always remember they dont always want to be cuddled and touched...
