Late hatch leg

[JaVelin]

Hi folks

We hatched out 27 chicken eggs. This was the first time we achieved 100% hatch. But the last 2 were pipped for 20 hours before they hatched and have fists and Sprattle. They have shoes now and we tied their legs together with a spacer. The trouble is one of the chicks sits back with his feet out front like he's reclining and can't get up. Is there another fix I'm missing for this? They are nearing 24 hours out of the shell

Thanks

Update.

So the slippers flattened out their feet snd tgey seem to move thier toes ok. but the splints didn't improve their ability to stand. It seems they can't extend their knees. They are either on their back or on their face. Is it time to cull these 2?
