ok...update on chick 5. Found him/her this morning away from the heater lying face down, not moving! It felt cold but as soon as I picked it up it took a breath...so begins a full day of nursing. I give it a gentle rub to get the circulation going, warmed up in my hands. It started breathing again ;-) I then put it back in the incubator...took about an hour but very slowly it regained consciousness and started lifting its head. I then started every hour since then..taking it out and helping it to drink. I made a sloppy soup from chick feed and water mushed up, I then basically dipped his beak it and tried to scoop some up...took ages. Now it is standing up in the incubator, walking around a bit and cheeping....I am very happy! It is not out of the woods yet though...I will keep up the routine hopefully until I can put it back in the brooder. I am hoping it will be ok in the incubator for while longer...but for now success!
