I see the need for stopping chickens ability to reproduce, nowadays, because there are SOOOO many being dumped or fed(inhumanely) to predatory pets.Too many people on cl handing over free cockerels/roos to "good" home only to have person receiving fowl feed them to their other pets(which is fine as long as long as previous owner knows what they're going for).Thats why I never hand a live animal over to someone. We just process ourselves then I don't have to worry.
