1-1/2 months ago I acquired a pair of proven Timneh Greys. These birds have been a pair for some time and are experienced at parenting. I, unfortunately, am brand new to this. 2-1/2 weeks ago I peeked into the nestbox and discovered 1 egg. I have tried not to disturb them, but did peek in 2 more times since then. The second time - yesterday - I discovered that the egg is cracked. I do not know if I should take it out or leave it there. If I remove it, will she lay another. She has been in the nestbox almost continuously and only comes out once a day and then for a very short time. I assume he has been feeding her. If anyone can help I would greatly appreciate it. Thanks.
