I got 4 ducklings yesterday.All Anconas.Very layed back most of the time. We had a Khaki hen who was being chased and raped and had begun staying in the woods,and not returning back home till the next morning. We put her in the "Grow" out pen with 4 ducklings.Thinking it should all be okay. The ducklings are attacking her.Making it VERY obvious ahe was not accepted.She doesnt fight them,but they fought are runner duck and are jumbo pekin drake.Of course they lost but had the guts to do it. Anything i could do to stop this bad behaviour?
