help on new bought bulbophyllum phalenopsis

[catasetum-ian]

hi, i am a newbie here. just bought a bulbophyllum last week, there was a new shoot arising so i bought the plant assuming its a healthy plant. this is my first bulbo.
after five days of keeping it, i notice that the new shoot is not growing and also black spot arising from the leave and some of the black bulb as well
i took out the whole plant just to found out that there is not root formation (just repotted i assume) and the funny thing is that they nursery attached a piece of chicken dung on the black dead roots. ....dunno this is right or wrong but i removed all the dung and wash with tap water till clean
i trimmed away the leave leaving one left, cut black bulbs away leaving two and off course the shoot as well but the shoot is turning yellow little bit
MY QUESTION IS NOW I PLANTED IT ON A NEW POT, SHOULD I WATER ON DAILY BASIS OR STOP WATERING TILL NEW ROOT OR SHOOT APPEARS??
ANY HELP IS APPRECIATED, THIS IS MY FIRST BULBO, SO REALLY NEED HELP HERE
