Maybe it was splayed legs because today, after having their legs splinted for almost 2 days they seem so much better. I've taken the splints off, they've both been a bit wobbly and one was walking backwards more than it was forwards at first. I'm keeping them separate from the rest of the chicks and I'm about to read up more on splayed legs. I don't want to take the splints off too soon so I need to find out if I'm doing the right thing.
I'm glad they're doing better. you read the thread blooie linked, right? I think there it might say a week? So I'd maybe keep it on the rest of the week just to be safe.
