they are actually happy to see you and if they don't step onto your finger that's because they probably don't know what you are trying to do try talking to them more get them to feel comfortable to seeing you and if they don't want to be touched then that's when you give them their space so they know that they have that type of bound with you.
Wont they still have the same genes, so they wouldnt be immune to anything? Like if you breed grey with blue they have different genes and can have different immunities to different things
