Maintain clean water and bedding to prevent disease

Change drinking water 1–3 times daily, dump and refill swimming water every 1–2 days, and manage coop bedding through either deep litter or frequent full replacement. Ducks foul water within minutes and produce droppings that are 90% water, making sanitation the single biggest health management task. Dirty water harbors bacteria, coccidia, and parasites. Wet, stale bedding breeds Aspergillus fumigatus, the mold that causes aspergillosis — a frequently fatal respiratory infection.

Why It Works

Most duck diseases are directly linked to poor sanitation. Coccidiosis spreads through fecal-contaminated water. Aspergillosis spores thrive in damp, warm bedding. Botulism develops in stagnant water containing decaying organic matter. Maintaining clean conditions eliminates the environmental reservoirs where these pathogens reproduce. Ducks that swim regularly in clean water also maintain better feather condition, which improves insulation and waterproofing.

Tips

• If you smell ammonia at duck level in the coop, bedding needs immediate attention
• Dump pool water onto garden beds rather than letting it stagnate — it's nitrogen-rich fertilizer
• Use nipple waterers as a supplemental clean drinking source between open-water changes
• In summer, dirty standing water can develop botulism toxin within 24–48 hours — change it daily without exception
