I feel so helpless to save this last tiel egg. My pair that raised a successful clutch last year is not doing so well this time. 3 chicks hatched out of 4 eggs. I keep finding them cold in the corners of the box. I pulled the biggest out yesterday morning thinking it was dead. It warmed up under a lamp. I was able to give it a few drops of formula and put it back. In the afternoon same thing. This time it's rump looked red and bloody. I tried to warm it up and again tried to feed it but it died. This morning I went out and noticed both parents out of the box. Again the last 2 chicks were cold. One was dead and the other died a bit later. There is one egg left and I can see a fully formed chick with a nice air cell. Right now it's in an incubator. I just dont know what to do if it hatches. I'm not prepared to hand feed one so young. I've never done it before, and I do have to go to work. I dont know if I can give it back to the parents. I've brought the box inside from my outdoor aviary but they wont even go in.
