I have a 4 day old call duckling and his feet turn in. It doesn't bother him and he doesn't trip up but I don't know if I should do anything? His 2 day old sibling is also slightly turned in. They are being fed on duck starter. Sometime the older one will lie down randomly, like earlier they were running round my room and they food a pea skin and the older one got it and then was lying down when trying to swallow it. What could this be ? Can I do anything about it?
