Here we are on day 4. Duckling is actively drinking. We are using SmartWater which is which is vapour distilled water with electrolytes added. We have also put some Marigold Engevita yeast flakes into their crumb which is then soaked in the electrolyte water (we were told it was better at this small scale than brewer's yeast and have added it at a ratio (UK measurements so just the cutlery!) of one and a half tablespoons to a cup of crumb. They seem very typical in them themselves, calling and moving around. We are spraying the nub with Vetericyn and it appears to be yellowing. Still cleaning the vent regularly as it getting a bit messy and we want that area clean. Poop is mostly white water waste and green meconium. Getting a little concerned baby hasn't actively sought food. Tried various levels of mushiness and also a small spider! Going to keep this updated in case it's ever useful to someone else but can't help feeling worried.
