Hi so i have a muscovy hen sitting on an egg and were now on about day 35-37. When i candle the egg you can see movement and its sort of like its pushing on the air sac and that but i cant tell if its pipped internally or not. It has looked like this for a good 4-5 days now. Just dont know what to do can anyone please help? Picture ive added looks identical to how mine looks but it only looks like this after the light has been shining on it for a couple of minutes
