My African Grey girl just laid an egg (which may have been fertilised by the boy, although she did lay 2 blanks a few years ago) and she isn't sitting on it. She laid it on the floor of the lounge when she was out playing. I moved the egg into a nestbox in her aviary, then put her into the nestbox with it. She shuffled the egg about for a few seconds then came back out. 10 minutes later she went back into the nestbox of her own accord, moved the egg further back, then came back out. But for the last half hour she's not been in there. I can't find much information on the first days of eggs on Google. Only one webpage said anything - that she will wait until the 2nd egg is laid before sitting. Is this correct? Will the first one not die if it's not kept at body temperature? Also, how old does the egg have to be before I can candle it? I have bred Greys (and conures and Amazons) years ago, but the other birds always knew what they were doing. This one doesn't seem to. Please give me some advice so I know if she's doing it right.
