My Black Australorp just hatched 4 chicks yay! There are 3 eggs in the nesting box that are still developing, but my hen has already left the nesting box with the chicks that have already hatched. I would love for the 3 remaining eggs to hatch too. I do not have an incubator, and I really would prefer not to buy one because I would probably not use it beyond this time. What can I do to 'finish' hatching these eggs, if anything? Thank you in advance for your advice and help!
