I am the Feed Manager at Baell Mercantile Company located in Moultrie, Ga.
We have Chick Days every year. One of the biggest mistakes that people who are new to buying chicks make is failure to purchase certified "sexed" chicks.
It's nearly impossible to tell the difference in a three day old male chick and three day old female chick to the untrained person so don't fall for stuff sales people (or "old timers) tell you about picking them up by their wings and seeing if their feet dangle or go out straight., this is an old wives tale that has about 50-50 chance of being right, or wrong. Sexed chicks cost a few cents more but it is well worth your investment to ask the right question when buying the chicks and pay the higher cost to be sure you are getting what you wanted. Ask your salesperson if the chicks were sexed at the hatchery. That's the safest and easiest way to be sure that you are getting an egg layer instead of a a "crower". It's really upsetting to spend the money on all the stuff you have to buy to grow these chicks out and find out that instead of the delicious eggs you thought you were gonna get, your getting a loud, scratchy RR-RR-RR-RRRRR.
Make sure to buy "sexed chicks", you'll be glad you did!
