I am running a hatching project in my year 1 classroom, the eggs have been in the incubator for 15 days, (I bought them on ebay so don't know when they were laid) and I think I only have one viable chick - I am worried about it being alone once it has hatched. Am I right to worry about its emotional health? Any advice as to what to do for the best would be most appreciated! Thankyou! p.s. I have another embryo that isn't as developed as the one I mentioned above and I think the air space has got bigger, is this probably a dead chick?
