I am not aware of any chicken mammals around here. All the birds that I know skip lactation.
Only mammals produce milk. Birds such as chickens do not produce milk, not even in South America.
No, only mammals produce milk for its young.
Yes, Llamas do produce milk for their young. They typically produce 60 ml of milk at the time that she gives birth.
No. Only mammals produce milk for their young. The only birds that produce milk are pigeons.
yes! Well not all birds, some of them such as pigeons do. But it is sort of gross, its not like a calf sucking the milk out of its mother, the mother bird hacks up the milk into the babys' mouth.

Nope. Nipples are used to provide milk for the young. This occurs in mammals and not birds. This is why you do not see chickens suckling.
You'd have to give birth to young first before you produce or leak milk.

Yes. As mammals, cows do have hair/fur and produce milk for their young. The milk forms in the cow's udder and is available to the calf/calves at any of the four teats.
I believe that Pigeons and Flamingos produce a 'crop milk' that they feed to their young by regurgitation.
They do produce a substance similar to milk known as crop milk which they feed to their young. However, while similar, this is not the same substance that mammals, like cows, produce.
