I used to buy my organic (not certified) chicken from Grafer at the El Galpón de la Mutual Sentimiento at Lacroze - Chacarita.
Great quality, texture, taste & smell (or lack of) LOL
However they are not selling there anymore due to the lock down. I just called Patricia Grafer - to find out...
I have been looking for Organic Chicken as well and found this company called Cocorokeen in Carlos Keen. The owners name is Dario. They do deliver to CABA. However they only sell whole chickens. Price per chicken is ARS 1,500.-. Average weight is 2.1 - 2.5 kg. the minimum order is 3 chickens...
Interesting Link about Global Cellular Network Coverage.
