He seems to go in phases. Sometimes he hobbles around pushing off both legs - one is weaker but he uses it and sort of gets around. But sometimes he just isn't using that leg at all and rolls straight over and gets stranded on his back. I've tried some electrolyte and will keep doing so.
Feeling really down today. Our last hatch only 2/12 made it, they just went out in the coop 2 days ago and today I found them both decapitated. So sad. This is the same week that a fox broke in and took 10 layers and a broody duck. And then yesterday's hatch was only 1/12 and he's splay-legged. I seem to be getting all the bad luck. I'm going to try a dry hatch this time as despite my fancy humidity pump and following the instructions perfectly I am getting horrible hatches.
What kind of incubator do you have and what instructions are you following? You need to find out why your hatch rate is so low before blaming equipment.
Really sorry for your losses though, and hope you get the fox soon!
