I have thought about that too, and I am wondering IF they have had that problem. How to find out is the question.
I don't know what is going on with my chicks, but I do know that I have learned something that I did not have a clue about a month ago. That GMO fed parents are going to have GMO chicks, and in a 1-2 year generation those chickens will be sterile, and won't be able to reproduce. There are studies out on this. I was just talking to a person this week about that.
Blew my mind. So, with humans, it will be the same thing, only it will take longer for them to become sterile. The study I was talking about with a woman who is very knowledgeable about GMO, said that they have proven facts that pigs that are fed GMO feeds, will become sterile within 2-4 years after ingesting the GMO products/feed.
SCARY!
