No, it does not absolve anyone about anything. What it does is encourage people to allow nature to take its course. If you see the bird is suffering or needs vet help, get it; but I am sure you would agree most people make the problem worse when they interfere is the natural process of reproduction. Why is the bird starting her third clutch of eggs? Where are all the eggs she laid before beginning this third one? With my outlook, she would already have a large pile of previous eggs staring her in the face every time she looks at her "nest" site and would feel no reason to add to it. If she is having unusual hormonal influence to lay more, I would allow her to do it, add to the pile, as long as she remained healthy and happy. Humans interfere too much in their bird's instincts and when we short circuit their instincts that is when the poor things literally kill themselves trying to answer nature's call.
I suggested the owner pile up all the bird's eggs, let her add this next clutch to the pile and then LEAVE HER ALONE WITH HER EGGS. Don't touch them, move them, even look at them cross ways. Let the hen see her riches and let her feel fulfilled. Changing around the cage, altering her food, changing her environment just makes a hen who is feeling broody look for a better place to lay eggs and fulfill her hormonal mandates. Instead, back off. Let her lay and watch her. If a health situation develops, deal with it. But as long as she is healthy and happy, leave her alone.
Go ahead and stand by your beliefs. I think it is great you found a novel way to prevent triggering your birds' reproductive instincts. Hope it continues to work. I am not saying my way is better. I am ony saying my way, so far, works well for me.
