Late egg from rotten nest - can I discard it with a clear conscience?

[Abigrayl]

Good day, my first time mommy hen was sitting on one egg, so the same or next day we added 6 more that we bought. Her little egg hatched on Wednesday and today is Sunday. She hasn’t left the nest. 2 eggs exploded while she was sitting on them. Yesterday 2 more exploded. And 1 broke op (did mommy open it) en to reveal a dead chick that had not absorbed its yolk. The last egg I am afraid will explode. I want to put 2 bought chicks under her. Can I remove that egg with a. C clear conscience? It’s had like 4 eggs explode on it. The float test was inconclusive. Please let me know what you think.

Have you candled it? This involves shining a bright torch into it in a dark room to look for movement. The torch on a smart phone is bright enough. But there is a good chanceit's no longer viable.
