We do not recommend that broiler chickens are kept as pets as their quality of life is badly compromised by their genetic selection for fast growth and weight gain. Other than this there are enormous variety of chickens to choose from that can make excellent pets. These are just a few of the common ones.
Isa Browns are very popular. They are moderate in size weighing about 2 kg, have quiet temperaments and are excellent egg layers. Rescue groups will sometimes source hundreds of birds from commercial flocks when they are past peak egg laying to try to find pet homes for them. Other good egg layers include Rhode Island Reds and White Leghorns but these birds may not be as placid as the Isa Browns, which, incidentally were developed from crossing the other two varieties.
Larger breeds include Plymouth Rocks, Sussex and Orpingtons. These are all nice if you have the space but they are not as good layers as the Isa Browns and you need to watch their weight as they can develop bumble foot if their diet is poor, they get too fat and are kept on hard surfaces.
Common, attractive, moderate size varieties include Wyandottes, Barnavelders, spotted Hamburgs and Australorps. These are not generally as good egg layers as the Isa Browns but, their temperaments are generally good, they can look lovely and they may be at somewhat less risk of female reproductive disorders as they get older that the high producing varieties.
Bantams are miniature chickens. Their eggs will be smaller and not as numerous as with Isa Browns but the eggs can still be used as you would any other kind. Silkie Bantams are a fluffy variety noted for ‘going broody’ and are sometimes used to incubate eggs from other types of birds, even parrots.
There are lots of other varieties, including Aracanas (these lay blue eggs), Polish, Cornish Game, Naked Necks, Frizzles, Belgian d’Uccles, Cochins, Minorcas, Faverolles and Sebrights that we see from time to time and can make delightful pets for the right owners. By all means do a Google search and see which type may appeal you.
