I have noticed I can sometimes hear my ducklings breathing through their nostrils and I'm wondering if its normal and if I should be worried? They get a bath every day so have the chance to clear their nostrils then and I clean their brooder out every day. I don't know if I'm just noticing it more because they are in my room so I hear them now while I'm trying to sleep whereas before the ducks were downstairs or if they shouldn't be doing it...? Like i said its not all the time but I'm very worried.
