So we lost a duckling yesterday. His brother was pipping also. This morning he looked like he was struggling a bit- he was coming out ass first. Very strong, shouting and flapping the wing and foot he’d managed to get free. He popped his head out this morning. There’s still a small fingernail yolk sac attached. He looks a bit knackered (understandably) and is laid at the bottom of the incubator. He’s breathing ok and shouting. I’ve got chick crumb ready for when he needs it. Will I need to feed grit along side this from the off? Do I just leave food there for them to help themselves or feed at selected times?
