I have two female Muskovy ducks. I got one first and then was looking for a friend for her and found one about the same age (8 months). The one is got first is relentlessly bullying the new one. I thought she’s be happy to have a friends since it was just her and the chickens and I know ducks like to be with other ducks but she won’t stop biting her neck and attempting to pull her feathers out. Do I get rid of the new duck and just let the original one be a lone duck? It’s been 3 days and the behavior has gotten no better. She literally seeks out the other duck to bite her. And the other duck just lays down and lets her bite her. She hasn’t successfully removed feathers but she grabs them and shakes her head back and fourth trying too.
