I'm going to guess that it's like many other businesses where customer service is either outsourced or compartmentalized. The person you reach isn't in the chicken business, they're just fielding calls with a booklet of scripted answers. Ask something that's not in the script and they have to weigh whether it's important enough to escalate.Diligence? I don't see it.
From the replies people have been receiving from Hoover's over these hybrids it seems they know next to nothing about them.
They are supposed to be a simple sex link hybrid. Pullets being blue and cockerels being blue barred.
How does Hoover's not know this or why are they unable to answer something as simple as how to tell the sex on one of their sex linked hybrids?
