Poultry-Yard in Bandra

Nice old card I got from Ebay. It is a card from Bandra, the St.Josephs Convent which show us some chickens and the people who lives there.
The card was shipped on April 25th 1931 and was send from India to Belgium.
The postmark say to us that it was there on May 10th 1931, there is no name of city to see on the mark. The Postcad was send to Soeur Marie-Monique in Cointe (Near Liege-Luik)
You can see how to get a lot of chickens on one picture, just feed them.
On the backside of the card, show also, you see" Bij Europe mail" what does that mean, maybe because India was British they have European mail there? Or the sender did not know what she was writing about..
