So this is my second batch of a second attempt to hatch call duck eggs. They are significantly more difficult than others e.g. Pekins which had a near 100% hatch rate. The first batch of my second attempt I had 5 fertilised and only 2 hatched (40%) using a better incubator with humidity control...
I managed to train my ducks with the Grandpa's feeder. I needed to use loads of mealworms then they got spoilt and needed them every morning on top of the normal pellets.. which semi defeated the "fully automatic" purpose.
When one duck learns it then they kinda teach each other.
The beak is crusty near the top and since today one bit broke. I suspect infection rather than physical but otherwise he is eating drinking playing well. Is it contagious? Topical antibiotics/antifungal? Others in the same house seems unaffected.
