Care Tips for the Feeding Parents.

 "Once or twice a month a special bath of  one tablespoon of Epsom Salt diluted in one gallon of water should be provided to all types of birds, especially the feeding (canary)

parents. The Epsom Salt bath can help to neutralize any sourness in the digestive system. Remember birds only have their beaks to do most of their chores. The adult birds, especially canaries, tend to eat their young's excretions when cleaning the nest and consequently, experience sour digestive systems and then will not  feed the young. The parents also tend to consume excessive amounts of rich foods and again may not feed the young due to an upset digestive system. By supplying the Epsom Salt bath once or twice a month and especially when  the parents are feeding the young you can alleviate most of the above mentioned because birds drink before bathing."
