I'll throw my two cents in for this too.
The animals that we eat aren't over populated. We eat cows, chickens and pigs. WE as humans farm these animals for profit and for consumption. The animals that are grown commercially for meat are put in small areas and only grown for a few weeks until 'mature' then they're sent away, and another batch is brought in. Now a REAL farmer, only grows as many cows as his land will hold and as many cows as he is capable of feeding through the winter. For commercial farming, it doesn't work like that, its just as many as you can shove into a pen so they're all still standing up.
As for the cage free, certified organic stuff. Thats a joke. Just because it says their cage free doesn't mean the animals are roaming beautiful rolling green pastures, it means that they're not in their own cages. For chickens, cage free means that 200,000 chickens are put into a 40,000 square foot dirt patch with a roof and feeders/waterers, but they're not in cages. A battery hen on the other hand, is in a small cage, so she is not cage free. The organic part of it, the animal only has to be a certain percentage organic to be able to have organic slapped on the package.
Okay, now on to what the thread is really about.
I think that since you humanely grow and raise your chickens, you should be able to comfortably eat the eggs. I also have my own chickens and I love her eggs. I prefer to eat homemade eggs to store bought eggs. I like to know what my chickens eat, where they sleep and know that they're not pumped full of chemicals and antibiotics. Plus, your girls work so hard for their eggs, why would you want them to go to waste. I love collecting fresh eggs, because its such an amazing thing for a chicken to be able to produce, every day! I don't think it takes away from your being a vegan, its good protein and you know how they're taken care of and what they're eating.
PS. Sorry for the rant. I'm totally for veganism and meat eating. But population control isn't an issue, people are more of an issue than the cows.
