A dirty feeder does more harm than no feeder at all
How often
Every fortnight at minimum, weekly in warm weather. Hot soapy water, rinsed, and dried completely before refilling.
Moving it
Move the feeder every few weeks. Droppings accumulate underneath and the ground below becomes the main infection route.
When to stop
If you see a bird that is lethargic, fluffed up, and struggling to swallow, take the feeders down for a fortnight and clean everything.
