So I have 10 female ducks, two mallards that are 4 1/2 months old, two black runner ducks that are 4 months old, and the rest I recently bought are khaki and Swedish girls that were hatched early may or late April. I’m very new and clueless about ducks(loving them and everyone on backyard chickens.) I’ve been reading about when they should start laying, and I’m not sure exactly the timeframe for each breed. Any advice and stories.
