Of course there are no guarantees on BYC either. Folks should use common sense. But there is a FEEDBACK section. You have the opportunity to get to "know" people and breeds and get referrals.
There are bad breeders here and uninformed ones and ones with few standards for their stock. They don't get good feedback or referrals. I've been offered chickens and eggs I didn't take, having learned enough about the breed to know what I was looking at. Sometimes I've been warned away from some breeder privately by friends here.
No, they aren't miracle eggs, but you can get eggs here, from people actually caring about the quality of what they produce, including meeting the standards for their breeds and their reputation, that's hard to mimic in other "sale only" forums.
This is like an all breed club, there are some bad "eggs" but there are some people doing the best to care and raise and sell excellent specimens of the breeds they're invested in.
I prefer that to the anonymity of
ebay or eggbid. Shows are good places to find people showing breeds who may have eggs available in your area. I also buy from breed club members in the breeds I'm interested in.
Lots of good and bad sources for eggs. Part of preventing ripoff is learning before you buy. And using your head.
Let's start with knowing enough not to buy hatching eggs frome someone who doesn't have a Roo to fertilize eggs. But I figure common sense can sort out a few more people as well.
