Our chicks have come from a local hatchery here near Davis,CA. They only produce one breed of egg layers so to differentiate the flocks we have put coloured spiral bands around their legs. These work well until for some unknown reason one chickens leg will swell and we have to catch her and removed the band. So we decided to take another route and get different coloured birds for each flock. These are black sex linked egg layers from Welp Hatchery. http://www.welphatchery.com/
The males hatch with different colours so it is easy to sort them so that we only get females. They will start laying eggs in January.
