I have been very pleased with MannaPro Poultry Conditioner. A number of birds showed remarkable improvement, marked narrowing of the tail (piped), improved wing carriage, and overall tightening of their feathers and health. Not being able to put birds down, I keep a special cage just for the old timers and they perked right up on MannaPro. But what really impressed me the most was "She".
Being a last year bird (2011), "She" kept her sex a secret until I feed her MannaPro Poultry Conditioner and the very next day her secret was out, "She" started singing just like the other males!! To test it, I took him off the MannaPro and sure enough no singing but each time he gets MannaPro he starts singing again!
Hope He won't mind me nicknaming him "She"....
("She" is a hard bird to photograph and was flying wildly till I thought I would not get an acceptable picture. "She" looks better than this as this was the last shot I took and he had been frantic for a half hour as I just kept shooting.)
