Day 25 still no signs of hatching?

[mother of many]

I have a Cream Legbar egg on its Day 25 and still not out. It was set with 4 other eggs( one died at Day 7) the others hatched on Days 17 and 18. They were all incubated the same way but this one egg isnt doing anything. I have candled it since Day 21 to check and thought I saw signs of movement the past couple days but i fear my eyes may be deceiving me. What should I do?

Candle it again. Doesn't hurt. It's odd the others hatched so early. My CCLs hatched out on days 21 and 22. Does it smell?
