I haven't looked at the picture and I don't know the situation but I've had chicks like that. They just sleep under the bulb in the brooder for 1-2 days, they don't move and eventually slowly they start moving and walking and are fine.g
I have the one that had lost a little blood by separating from the egg to fast and while its breathing fine and pecking at itself and chirping it has never tried to stand or raise its head it propels itself across the bottom of the bator but that's it. I'm not sure if something is wrong with it. or if it is weak from the blood loss. it was about a thimble full if that helps.
