Oh, bl**dy hell!
Right, that's it, I give up, I'm off!
Don't post a thread if your not going to have the maturity to contemplate the answers.
Jesus Christ, the world is full of "Possibilities" but clearly your too young to accept that.
As previously stated, you have had good advice from a lot of people, people who have been trying to TALK to you about Veganism, your health & chickens. There are really no more good answers to your questions!
This is a pointless thread since you won't accept any answers from people more experienced than you.
My last suggestion is "Give up the chicken keeping". Seriously. They are not toys to be manipulated at will to suit your "hobby". Because that is really all Veganism is. If Vegans were REALLY serious about making a real difference then they would not have children to add to the population.
But, sadly many Vegans & vegetarians (Although not all, there are still some with true morals out there) push their pets onto vegan diets that harm them, force their kids to be vegan / vegetarian & they preach about being Vegan or vegetarian to people who, quite frankly, couldn't care less & live in the real world where there is meat & vegetables & fruit. The list could go on & on & the matter is NEVER up for discussion because Vegans / Vegetarian's always know best, even when some of the bad truths lie right under their noses. Its no better than a cult when your attitude is wrong.
Even your parents have told you it is not healthy. Do you think they say it to be mean, because they have something towards eating meat? NO. Its because meat, fish & dairy is all part of a healthy diet.
You will end up ill if you try to live of calorie milkshakes & Vitamin tablets like you suggested, it won't make up for healthy balanced meals in the long run.
You should be glad your parents have been concerned about your health & you should listen to them more.
I hope this thread closes, its just pointless & ridiculous.
This is what you sound like:
"I have chickens, but don't want eggs"
Now, read it again & register how idiotic it sounds.
Let your chickens be chickens & stop this nonsense.
Its a good job your not my kid cause I tell you now, you'd get a right backhander for being so dense!
