I have Serama chicks who are on day 19 of incubation. None have pipped yet but one has liquid above the air cell and I am afraid it will drown when it pips internally. I have not increased my humidity and have kept it between 30-40% through the incubation so far. Can I externally pip the egg and drain the liquid and then cover it with wax so that he/she doesn't drown. Any suggestions???
