disqard, I don't take any offense at all. If nobody told me I was wrong, I'd stay wrong. As I mentioned in my earlier post, I'm welcome advice. Now for my counterpoint and please don't take this as arguementative but rather as discussionary: Many years ago when I was looking into getting chickens (it took three years to come to fruition) I picked up a book whose title and whereabouts are now a mystery (my four-year-old took it for a coloring book.) It was a fairly comprehensive, albeit thin, book that went from hatching to slaughter and all the steps in between and it was recommended feeding medicated chick feed up to 8-12 weeks old but not beyond 12 weeks because it could interfere with the natural developement of their imune sytem. That makes sense to me and considering that the guy at the feed store pretty much went along with that and I hadn't gotten any information to the contrary, they were switched at eight weeks. I wasn't looking to accelerate the laying process, I'm a patient person. I only wanted to do the right thing. Do layer pellets pose a danger to young developing chickens? I guess they might, I don't know but I hadn't heard it before now. I'm not saying that your information is suspect, I think it makes sense and I would have considered it had I been aware of it at the time. Again, no offense taken. In fact, thanks for something to think about for when I need to get more chicks.
