Need help with orphan chicken eggs almost ready to hatch

[kitara5454]

Also, there are 19 eggs!! so if they all hatch,,,, oh my goodness! LOL I already have 15 chickens....LOL what's 19 more??? LOL LOve it! One thing that concerns me tho, is that the last batch she had, only a few hatched and we didn't know it and the snake or something got them all except one, which I brought into the house. but it was not right, it could not stand up unless I helped it or it leaned onto the side of the cage. It also was shaking like some neurological problem. I kept it for about 2 to 3 months to see if it would get better and give it a chance, plus I couldn't help but try to save it...... but it was not able to eat or drink without my help holding it up... it was very sad and we had to put it down. it had a very nice personality too..... beautiful silky black feathers.... I never had to do that to any of my chickens before..... very hard to do..... Does anyone have any idea as to what the little chicken had?
Thank you
