Sparrow is about 6 weeks old and doing well. He is in the chinchilla room, so it is cool in a small zoozone cage. I don't have anything bigger for him to go into in the house- bar spacings still too big in most things. He needs more space as he is very active. He is not vaccinated yet but all my others are, and I'm wondering about putting him into a 6th hutch in the kennels, do you think this will be ok!
