seriously mine are vicious i wish that i had gotten all of mine at once but the colors werent all avaliable when they needed to be so they are all in different groups and everytime they go together there are major fights and its just been really stressful because the grey call ducks absoluetly HATE the snowy ones and the grey ones will leave the magpie call duck alone but if he gets near the grey calls they nip at him and then one snowy call duck only wants to be around the magpie but the other one attacks him constantly. So its just all one big mess
