Clucky cocatiel

Hi I have a female cocatiel that I think is very clucky.She runs around the house as though she is looking for somewhere to lay. She laid her first lot of eggs last year .which were unfertile.She had a little cardboard box that she use to play in,that is where she laid her eggs.Should I give her another little box?Im worried she will become egg bound if she can't find anywhere to lay her eggs.I have also bought her a little mate (male) cockatiel which is only six months old.Im sure he has'nt done the mating thing with her yet.Looking forward to receivind some advice Thanks
