They say that good birds are not cheap and cheap birds are not good. They also say that you get what you pay for but I am not convinced either statement is entirely true. Fuzzy up above bought cheap chicks at the number one place you should never buy birds at, a swap meet and local farm auctions are not much better. A lot of 'backyard' breeders don't have the knowledge it takes to keep peas healthy which is the exact reason this forum is here, to share and help people with their birds.
Knowing the breeder is important. You need to make sure they know how to preventively diagnose and treat birds for illness. They need to be knowledgeable and be able to help you with your birds. They need to know the genetics of the birds you are buying and share that with you so you know what good pairings to make.
IB's are considered to be the 'common' birds that cost the least. Color mutations and special patterns make the birds more expensive. Having the DNA test already done is a big benefit to the buyer and adds another $25 value to the bird if not more.
Many people want to buy chicks so they can have a special relationship with them as they grow up. Older birds are not always friendly, especially from a big breeder who does not have the time to spend with the birds to make them friendly and not flighty.
There are not any chicks in the US at this time, or at least not any over a couple of weeks of age. Make sure the person you are buying from is legit, there is an awful lot of scammers loose right now. Do your homework and check them out so you don't fall prey to them.
If you are buying 2021 hatch birds for that $300 per bird is not out of bounds, I sell my yearlings DNA-tested cocks for $200 and $300 for the hens. If I have any leftover by summer they will be higher in price. Mature breeding hens are now around $400 for common hens and color mutations are even more.
