These baby chickens are between 4 and 10 weeks old. They are Commercial Layers which are bred for egg production giving you more eggs per year than standard breeds. They are sexed as hens and are about 97% accurate. They no longer need a heat lamp but are still fairly small and will need to be kept in a safe area away from snakes and other birds that may eat them.
Chickens are herd animals and rarely survive alone. Buy more then 1 chicken at a time
