Hi please can someone help. I have 4 adult ducks they are a saxony, Aylesbury, Kiwi Campbell and a Apple yard all girls. I hatch 3 runner ducks they are 6 weeks old for the last 2 weeks they have been in a small fenced off area out with the big ducks. Over the weekend I put them all out together and the big ducks keep chasing them around and the Little ones seem very scared I don’t know if I should leave them all out together or not. Please help
