I have been incubating for almost 4 days i candled day 1 and 2 didn't see any progress then i just candled an hour ago and i see the spider veins i also noticed a few have a perfect red ring around the veins and was wondering does this mean they died this is my first incubation i read as much as i could before starting incubation IM worried they will all die should i wait a few more days before I give up on them? or just throw them out
