I’m really concerned for my duckling right now since she just recovered from some sort of fungal infection last week. She seemed to be better until my dad put down some hay in the coop yesterday. She started to run and hit walls and start quacking and then flip over on her back and start flapping her wings and legs. Maybe it’s from our neighbors fertilizer? But I don’t think she’s put any down lately. Does anybody know the reason why and the cure?
