Hi, it is day 24 of incubation (of a chicken egg) and there is no external pip. When I candled it last night, there was no internal pip. Only one out of the five eggs was fertile so there is one egg in the incubator. I haven't seen the egg wiggle around, but every time I check it, it is in a different position. When I candled yesterday, the embryo looked a lot bigger than on day 17 and the air cell was really big. Despite this, the embryo doesn't quite look big enough to hatch. This may be because at the start of incubation, I didn't have a proper incubator (I only had a heat lamp). The temperature was hard to control, so I bought an actual incubator at day 5. This is my first time incubating, and I am really worried about the egg.
