Ok so as I'm only left with two ducklings. I decided to give them proper care... I m just really concerned about this one. It's crop seems to be full at all times. As you can see in the picture. . I'm not sure why it is or maybe it is normal?? I provide them with food all the time and don't remove it . Someone said that there crop looks bloated all the time and it seems empty at night when they don't eat food. But it is the same at night too... He walks around searches for food but he is not that active as the other one. I attach the picture of his poop too. It's very solid and a very little amount of water is present. Somebody tell me if this is a real issue or I'm just overthinking
