Ok, i have 4 ducks and a randy gander. he was trying to mate one of my ducks (blue swede mix) last week.. focusing on that one duck. This week he is enamored of one of my other ducks, and she is lying down flat, and extending her neck, while he sort of bites her head and neck... little nips... then she sort of freaks out and flaps over to the other end of the yard... then comes back and lays down again... is this some sort of 'come hither' sort of move? or is she sick? the other thing is that he tried to mount her while she was lying on the ground... not in the water.. she squirmed out from under him, and he fell over onto his side.... are my birds normal or totally strange?
