Thanks everyone. I must post an updated photo of Berry as she is becoming huge and weighs like a brick... She is now as tame as Chunky although it has taken a bit longer with her and I love her to bits. I have moved her into the Gabber Rex because it is the biggest cage and if I do decide to let her have babies I think it will be the best baby cage. Also she had developed a serious bar chewing habit, taking the paint off the bars and rubbing her face. Sid is now in the 24" Trixie and is happily climbing again. Chunky has just had a brand new Cambridge and Basil now has the extension back on his Imac. So we have been having a bit of a change around here - mainly to accommodate Berry.
I have used my newly acquired taming skills to work really hard with Basil, Sid and Fuzzy my petshop hammies. Sid is almost as tame as the 'breeder' hams but Basil and Fuzzy are still a bit nervous. Will they always be do you think? Is it because they just weren't handled before I got them when they were very little? Chunky and Berry have never had any fear (or Sid but I put that down to him being grey). Sorry I've gone on a bit!!
