Hello, I quickly wanted to check on the two eggs my tiels had laid. First was on 21st dec and 2nd I guess on 23rd. Going by the days the first has completed 19 days. I couldn’t see any popping nor any chirps. Today morning I just opened a tiny part of the egg to pass fresh air in. I also cecjed the chick is still alive inside. Shall I b waiting for it to hatch by itself or manually go fo it. And when shall I do it if need be?
