Oh my....you're making me a wreck just reading this thread. Calm down. Breathe.
Alright, it sounds like a. you need a hygrometer and b. your humidity was too high during incubation. You have a couple chicks who didn't absorb the yolk properly and that is why you have all the goo and yellow stickiness one them.
For the chicks that are out, Leave them in the incubator. Leave them be for a day. YES A WHOLE DAY! let them get their "sea legs" before you yank them out and do anything. 9 times out of 10 a chick will straighten itself out with practice. Just like any baby, it has to learn how to walk and get it's leg muscles in order. Granted, in chicks this take a couple of hours instead of months like in people.
You may have a splayed leg baby, or not. Give it a chance to figure out what it's doing. If it's not splayed, you may do more harm than good.
I know it's hard. I know you're a nervous wreck. We all are when we first start this. But SOMETIMES less is more. Less handling, less hovering, less meddling.
I have an incubator full of chicks. They are finishing hatching. I have one I know will need a bath. He's got egg shell stuck to him. I still have 4 more to pop out. All I have done to this point is remove all the broken egg shells. The humidity is fine, the temp is fine and they are peeping like crazy.
Amazingly enough, they know what to do more than we do. They are born knowing what to do. So relax, stay calm and let them finish hatching and drying out.
