Why nobody speaks in favour of hen and goats???????????

We often listen many people/ NGOs etc. in favour of animals and criticizing cruelty over them by human beings.But we never see anybody speaking for hen and goats that are killed with knives so brutally that it can hurt one's sole.They are kept in iron boxes that are heated to so much extent in summers that we can't even touch it.... We express our sympathy for other animals but never for these animals..Why do we discriminate????Do they don't have life????
