BLACK ROCK (sex-link)
The only commercial brown egg hybrid proven
for over 25 years to be
genetically suitable for free range
|
HARDINESS
Their thick rich plumage not only protects them from
all weather conditions but they have been observed to be less susceptible
to Red Mite. They love the outside, come rain, snow or shine. This
together with their highly developed natural immune system means they have
the potential to have a long productive life. We are often being contacted
by customers with hens over 10 years old still going strong, with a
good egg production, (dependant on local conditions, feed,
light, lack of predators etc).

|
TEMPERAMENT
Being very docile they are not easily stressed, e.g.
by over flying “things” and as a result do not need de-beaking. This makes them an easy bird to keep to organic standards.

|
VACCINATIONS
All chicks are vaccinated at 1 day old and for
I.B.
with H120 but due to an influx of some very nasty continental strains of
I.B. local conditions will determine the level of additional vaccinations
necessary. Salmonella Vaccines in Black Rocks are out, there has been no
recorded positive salmonella test anywhere in the country amongst Black
Rocks. Their use is nothing more than a commercial due diligence exercise
and causes nothing but suffering and cruelty.

|
FEED CONVERSION
Is excellent and is less affected by weather
conditions than other hybrids because of their thick plumage.
|
| END OF LAY
There is the bonus of a good white-fleshed carcass. |

BEWARE OF IMITATIONS
Black Rock chicks originate only from Muirfield
Hatchery so Beware of imitations and look-alikes which may cause
confusion, some unscrupulous dealers are selling other
black birds such as the Bovans Nera,
Hebden Black as Black Rocks. Check on the authenticity before
purchase, first contact an authorized Black Rock agent or
Peter
Siddons of Muirfield Hatchery direct.
