while doing research for the Fayoumi breed page I came across these studies and this information

"Three of the most interesting facts concerning this breed and what has
drawn a lot of attention is they have been found to be more resistant to
viral diseases and may also be resistant to salmonella, feed consumption
is moderately low for such a high energy fowl and rate of maturity. The
Fayoumi chicken of Egypt has recently been re−discovered and has been
exported to twelve different countries. In the 1940s, ISUâs Dean of
Agriculture, R.E. Buchanan carried Fayoumi chicken eggs home from Egypt
for the poultry genetics program. The plan was to cross the Egyptian
birds, with American breeds to produce hardier chickens, disease resistant
genes and cut cost of feed, with the end goal to strengthen the commercial
industry. Scientists in the U.S.A are currently mapping the genes of this
indigenous chicken to find useful characteristics for commercial poultry
production. Current studies in Ethiopia were conducted with the Fayoumis
and indigenous fowl found locally comparing the groupâs hatchability and
consumption rate. Focusing on the small farmers success providing him with
a faster rate of return. The problem is that the aggressive, high−energy
behavior that helps Fayoumis survive harsh environments in Egypt hinders
the birds' adaptation to commercial production settings. One of the
biggest factors has been housing this free−scavenging fowl. With todayâs
knowledge, scientists are trying to develop genetic markers to help
poultry breeders accelerate the introduction of disease−resistant genes
that can be introduced into the breeding of commercial chickens."
