I want to buy some chicks and raise a few for eggs and the rest for meat. it's cheaper to buy a "straighr run". Will the birds develop any of the gender attributes before its time to slaughter or will i have to let them grow past prime eating age to sex? On a side note (and maybe i should dona separate thread) i saw in an old thread that some described dual purpose birds as chickes you meat out after their egg laying life. Is this true? Is the meat of dual purpose birds not a tough? I am thinking australorpe and/or RIR.
