I got 2 10 day old mallard ducklings from Pampered Chicken, and after a day of socialization, have put them both in with my 6 2 week old sex links, my 6 1 week old BR roos, and my tiny rescued bantam from TSC. They are all getting along splendidly, after a couple of biting episodes between the SLs and the poor scared mallards... everyone is now behaving themselves. I'll post pictures of the whole crew soon!!!
