I started thinking about feeding my dogs factory laid eggs, free range eggs are twice the price
Is the dog bothered?
... they only eat human grade food mostly free range 99.9% of the time.
Hello... they are dogs - I don't know about yours but mine finds her own vomit quite tasty and considers anything marginally edible to be fair game.
dogs eat the chickens.
I really see the above as one of those "First world problems" that are not problems at all, yet beset those who have "enough". Does anyone really think that either dogs or the 2/3rds of the world who are living at a subsistance level are bothered about where the food comes from or how it is produced?
If you have ethical problems caused by keeping a dog, then you should not have a dog. A dog is not a necessity of life. In fact, if you are at all worried about the world, you should take up Survivalism
and be entirely self-sufficient (wear a fig-leaf, eat roots, live in a hole somewhere in the wilderness.... no, skip the hole, digging that would destroy the entire eco-system.
Seriously, if this is the level of your problems, relax and learn to live with them. Once you get rid of the vicarious, liberal guilt, life becomes much easier.
And if you'll excuse me, I am now about to eat lunch which is "Force-fed Roast Kittens marinaded in their Mother's Tears."
