Hi! I am new here and am looking to gather as much information as I can I am incubating Runner Duck eggs and on day 13 of candling I realised I had twins....each within their own sac....we are now on day 24....what would U recommend to do when it comes to hatching....I understand this whole scenario is bittersweet but we have got this far and if we can get through the next few days I would like to do all I can to try and help them if they reach hatching. Should I make a safety hole in the air sac? If so when....and how will I know if one is facing the wrong way? I’m guessing if it tries to pip I may see shadowing on the egg shell? This is my first experience of incubating and was not expecting to have twins by any means! Any advice will be much appreciated!
