I need some advice!!! I have two 10 month old female Muscovys who have recently become incredibly aggressive! One is picking on the other by chasing her and pulling out her feathers while the second attacks my feet! They have always been very docile, until I brought a chicken into the mix - I took her out again pretty quickly when I saw it wasn’t going well... Ever since the ducks have been acting broody despite not laying any eggs and not wanting to leave their kennel. This has been going on for over a month but the aggression appeared only a couple days ago - help me!!!
