One of my girls hatched a couple chicks the other day. They were all happy in a playpen I set up for them, she's a beautiful bird and was a great mother. Successfully hatched a dozen last year. I went out today to check on her and her bubs and she had died. Usually when one of my birds dies and crosses the rainbow bridge, I can determine a cause but this time I have no idea. She was in a playpen, just her and her chicks, that has soft mesh walls and a mesh roof so it can't be a broken neck or head trauma from bouncing after being startled. She wasn't egg bound and there was no blood or evidence of any foul play. It was like she had just laid down and died. The room wasn't cold, and there are no stressful factors in or around it. I've used it successfully for years for sick or injured birds and mothers. Unfortunately it happened overnight so I didn't actually see it happen. She had been dead for awhile when I found her this morning. Her chicks are both fine, just a little upset. I've moved them into a brooder for now until I can see if I can get one of my other girls to foster them. Does anyone have any ideas about what happened to the mum?
