Hi - thank you so much for your responses - our single duckling is over three weeks old now - so day olds wouldn't really be suitable - I have her in a run in the garden during the day, where my 8 weekers are free-ranging, so she does at least have some duck company - she's very attached to us tho - I'm hoping she will gradually integrate with the other youngsters when she is a little bigger. Thanks again, Juliet.
