Many thanks for all the ideas and keep um coming they are helpful.
Cuttle bone was the first thing I put in there and within 30 mins he pulled it off the side of the cage and threw it to the floor and attacked it further.
Baking bread till it is rock hard will not be a problem for me as I can't cook anyway.

Chip chews the mesh, but only in the bottom of the cage under the hay. Chip has got to go and have he brakes adjusted before spring (if he can) anyway as this is also another problem and I think this maynot be helping the cause.
I cannot really house Chip on his own because my living room isnt big enough for another cage.
I also found today that he has been chewing all my aerial cables and telephone wire when he comes out for a rum around. Boy does he cost me a lot of money. I do watch them when they come out but he goes behind the radiator where the wires are and I can't get to him. Now I have no wires in the living room and this will stop the little monkey. Only thing is now what will he chew next.
