Please help! I am new to having ducks. I have a 6 day old Peking duck that is limping and does not like to walk. She was fine yesterday and this morning. I feed them 18% dumor chick starter with nothing in there water. On the leg that she limps on she does seem to have a little lump on her toe. But I'm not sure if it is normal. What can I do to help her???? Please help..
