I'm sorry for the late reply, I actually underwent surgery earlier today, so I've spent a lot of time resting while having my mother care for the quail in my stead.
Overall, the little one is doing much better. The mass on its hind has receded, though we are still going to keep it separate until we are confident that it is fully healed up. It has been eating on its own, though not much, and we have been needing to assist it when it comes to drinking. It has a lot of energy and actively tries to escape our hands when we are holding it, so we are taking that as a good sign.
It's toes are curled in, in a way that makes walking around and balancing difficult. The little one's balance seems to be on it's ankle, rather than the actual foot. We are planning on giving it a couple of days before making "shoes" for the chick.
As for photos, I'll be willing to snap some tomorrow if you would still like to see.
While on the topic, I have some concerns about some of the other quail babies.
The first concern is that, today, we had lost one due to an unknown cause. Yesterday this individual seemed to have been doing fine, but later today we had found him laying on his side, legs kicked out. He was unable to support himself, and was even having a hard time holding his head up. He wouldn't eat, though he did seem to be interested in water. We separated him from the rest of the chicks, in a warm but smaller box, and when we returned to check up on him, we found him without any life. Does anyone have any ideas as to what could have caused this? Is it something that could possibly spread to the rest of the little ones?
The second concern is one of the living chicks. Ever since hatch this chick has seemed lethargic and strangely introverted, moving away from the rest whenever they would come near her. Not only that, but she was having a hard time walking yesterday due to a mild case of splay leg, which seems to have worked itself out. Today, though, she would just stand around with her eyes closed and head down, yelling at the others whenever they would leave her. I haven't been able to get her to eat, though I have gotten her to drink a little bit. Even when picking her up or gently nudging her to see if she would make her way towards the food or water if woken, she wouldn't care. She would just settle back down and pretty much ignore my attempts to get her to eat.
