Full Overview

ISA Browns are relatively new on the scene, originating in France in the 1970s. However, since their development, ISA Browns have become extremely popular in commercialised poultry farming and therefore common. This because they were developed to have prolific laying capabilities, laying upwards of 300 medium sized, brown eggs per year! Due to their extraordinary laying abilities, ISA Browns should be provided with protein and calcium supplements to ensure they have enough energy for egg production and maintenance of their feathers.

 

ISA Browns are noted as being great chickens for people new to caring for poultry. They are moderate in size (2-3kg), are able to stand a wide temperature range and their gentle, affectionate nature makes them and family friendly! These birds also require relatively low maintenance and while they love to forage, they can cope well with confinement. Initially, addition of new birds to a flock of ISA Browns may stir some trouble. However, this can be mitigated by introducing birds of equivalent size and ensuring that all birds have ample space.

 

One consideration when purchasing ISA Browns is that their prolific egg-laying ability is at the expense of their longevity. While they can survive for up to 8 years given proper care, the lifespan and egg-laying period of these birds is more commonly 2-3 years. After 2-3 years, egg-laying will not cease completely, but will be lesser than during the initial 2-3 years. Furthermore, due to being a hybrid, rather than a purebred, it is recommended not to breed these chickens. Any offspring produced are likely to have reduced egg-laying potential and suffer from health complications including kidney problems.
