Chickielady vaccinates her chicks. I don't think that means that her birds have issues. She knows what she's doing, so if people are going to be so picky about vaccinated birds, that's their loss.
I'd rather not expose my flocks to birds that could be carriers of a disease. Just because a bird has been vaccinated does not mean it can not transmit the disease to others.
If people want to delude themselves about the fallacies of vaccination and think that bio security can ever be air tight and rely on those rather than common sense and genetic sturdiness that is their loss. And their flock's loss.
Yep. Actually, we use it ourselves (internally, being around so many animals, seems like a good idea) and on the dog for flea prevention and lots of other things. The only thing I don't quite understand is why it would help harden shells (saw a few people talk about this recently) and I didn't think silica (primary component in DE) would help 'harden' a Calcium based eggshell... I'm missing some piece of info somewhere.
It can't. It's not you that's missing the info it's others. The only way that could be remotely possible is due to the same grinding and sharp edges that destroy the internal parasites DE could aid in digestion and absorption of nutrients that could in theory result in those changes.
