We had 2 adult pekin ducks and we had 8 four month old ducks (4 pekin, 2 runner and 2 rouen). First my male adult pekin disappeared no sign of him any where. Then mothers day weekend my runners, rouens and 2 of the baby pekins disappeared.....These guys are just vanishing..... We do free range them and they all go in at night and we close them down. No chickens have come up missing at all any ideas as to what is getting my ducks? I just find it odd that an animal would only target my ducks! There is no trace of them no feathers from a struggle NOTHING They were there when I got home from work and an hour later when I went to lock em up they were gone!
