That’s good news
Often when in to much pain they won’t eat
So I’m happy to hear baby is eating
Can you take pictures and videos of baby moving
Also how big was your son that fell ?
I am not sure as I haven’t had a break in any of my ducks
I do know with any leg injuries or issues giving some extra vitamin B complex just helps to strengthen
Also if you have medicam ( anti inflammatory / pain killer ) I keep some on hand I get from my vet in case I have any with injuries...
