They are easy pets, which makes their case even more 
for me. They are now in our make shift run chopping on some grass, they havent even been in the room with people in for quite a while. They are skittish but some naturally are anyway, my two youngest are still quite jumpy, they all settle with time.
I find that if you shush shush shush them when you feed fresh food, (I use mainly spring greens some apple and carrots) when you feed them they then associate that with good feeling, do that when you hold them, sit by the cage, etc, i doubt they will take any longer to get used to you that if you bought babies from a pet shop.
I have just spent best part of an hour bleaching the cage, its still not clean. i think it would probably come off with wire wool, but i dont have any, I have cleaned it best i can but had to stop as its raining and i only have a make shift outside run....bloody nightmare this is! Anyway, lots of shavings and loads of fresh hay, fresh food and water, Ive put a throw over the top of the cage so they can only se out the front, my house is very noisy, that may be adding to their skittishness (is that even a word?)
Anyway, need to give the wire of the cage a wipe over, but they are good to go.
Also the wire cage part doesnt attatch any way to the plastic base part. In truth if it were me I would look for replacement housing once fund were available. They dont have a place to hide in there at the moment, ive scoured the house but i cant find anything suitable, a clean plant pot on its side would do, doesnt need to be fancy for them to be happy :)
