This song is not translated right in some parts. For example, no te canses ahora doesn't mean don't lose your breath now, it means don't get tired now. A small difference, but it still is mistranslated. Anyways, I much prefer the song in Spanish, it sounds so much prettier.
I know Barred Rock's are reported to not go broody, and that is why they're good production hens. I have two barred rocks and upon looking in the coop today I noticed Esther was sitting in the box. She lays early in the morning, never the afternoon, so I opened the door to the garden.
A broody hen can be a godsend if you are trying to hatch chicks. No worries about incubators, brooder boxes or heat lamps...the hen will take care of it all. However, if none of your eggs are fertile, or you aren't interested in hatching any chicks, a broody hen is not something you want.
