I am sorry I cannot help but I am sure someone will reply that can. I am having a similar problem with a poor wee call duckling that someone gave me. It was bought at a car boot sale and passed on to another person I know who has call ducks. He could not keep it and asked if I could have it. How can people be so irrisponsible as to sell poor wee baby ducks at a car boot sale? I have left it in with my baby muscovies and it is now hiding. It went straight to the bunch of babies and tried to snuggle in with them, at first I thought they would accept it but I think the mum and dad are chaseing it away. I have five older call ducks but they dont want to know the baby call. It is beautiful too, a chocolate brown colour. I hope it gets accepted by the others.
