Hi ya'll, just have a question regarding the float test. This is my first hatch. I went and picked up 16 eggs from a local farm, turned out 15 were fertile and all have been progressing. I candled at day 7 and 14, and then last night at day 18 before putting them in lockdown. I have one medium brown egg that I didn't see any movement in last night, though it still had the air sac, but the rest of the egg was dark, couldn't really see anything. I tried the float test, and it went right to the bottom, but stood up on the bottom, and had no movement. I was afraid to leave it in too long because I did get one little air bubble come up when it was sitting on the bottom, so I was afraid it had a crack I couldn't/never saw. I went ahead and left in in the incubator, but wondering if that was the right move...any thoughts? Don't want an exploding egg!
