I do not know if that's what it was about. But these are the only information on calcium. It is written in blue - calcium carbonate. Green - absorbable calcium. Yellow - general calcium. I recently came back with a duck from a vet but he did not help me much, he gave me an antibiotic and sent me home. Unfortunately, there are no poultry experts in my capital.
This is an ordinary fattening feed that growers use on farms. (That's why I have it now). Today, the vet has still examined two poos that the duck managed to do. He stated that he had not seen such pure purses for a long time. There are no worms, but it is well-known that it would be good to give a pile of different days to study. I'm really getting more and more worried about where such an ugly change of pile.
Maybe I'm making some mistakes in nutrition? As I wrote earlier, I mix fodder with kitchen waste. I serve morning and evening. As a snack, you get cucumbers and green peas every day. And this is how he spends the whole day on the catwalk.
