My duckies just turned 4 wks old and spend their days outside the majority of the time, coming in to get locked up at night. They have feed avail 24/7 but are also really great foragers and love to do that when they are out. It rained a LOT last night so they ducks were brought into their coop early (about 4pm) as there is plenty of room inside for them, they had food and water avail inside. When I let them out this morning, they have been huddling together most of the day (it IS a bit chillier today) and when I took them some treats (peas ) I noticed REALLY smelly poo...looks and smells like human diarrhea. In case it is a food issue...they are on Purina Flock Raiser with oats and brewers yeast mixed in. Is this something for me to worry about, what could be causing it? TIA!
