I don't disagree about implant issues... only that it seems to be a rare practice in the USA.
I've had 3 Leghorns ~ 2 from Dan Honour's developing Buff line & 1 White ~ & absolutely loved them. They could be aloof as chicks & adults but do interact a bit w/ humans in spite of their mostly independent nature. As a kid my folks raised large flocks of White Leghorns so I have history w/ them.
The two only negatives for DH & me were the overly floppy combs always covering one eye or the other & frostbite worry, & of course, worry about future laying issues. As our Legs got older, they became increasingly aggressive to the gentler breeds in the flock. We gave them to the neighbor who had originally gifted our White Leghorn to us & our 3 Leg hens were doing much better in the neighbor's layer flock which included Marans, Orps, Sussex, OEs, EEs, & other Legs. We visited often & got to see the 3 hens. At 5-yrs old the hens were still alive & the neighbor had no health issues to share which made us happy. They moved away to a big out-of-state farm so no idea how they ended their lifespans but a 5-yr age record so far was a plus.
