I have purchased some chinese quail hatching eggs from ebay. We incubated them in our homemade incubator, stopped turning after day 12 & started waiting for signs of hatching. Yesterday we got to day 18 & still nothing so we decided to try to float test the eggs. Unfortunately the one we took out got dropped & cracked, then a little beak poked out. Not knowing what to do we put it back in the incubator. It is still moving about but doesn't seem to be making any progress getting out of the shell.
Everything that I have read on the internet says that if any hatch after day 18 they will probably die anyway so I'm unsure what to do now. Any advice would be appreciated.
