hi dan4,
how about shower in bathroom?i guess our shower its too strong for him,so u might to buy the softer one n try.jojo never come to bowl too,i guess he dsnt feel comfort to jump inside bowl because of his long tail.
at beginning he hates the spray bath n always fly away but i spray my self in front of him n show him how good n fresh is it for few days,he likes it now!!when i spray him, he lift his wings open n start to do small dance,soo cute

i spray him from above of his head but quite far away to make soft rain effect.n slowly i can make it more near n near him n now he accept the spray bath without any problem.(after spray bath he can get small nut also n now he beg me every morning for spray bath)
about the bowl for bath,i tried many times,it never works.he just play around n throw the bowl to make mess n i need to mop so i stop it.once i give him huge big bowl n he tried to step inside but he realized his tail not fit inside,he go away from it.i guess stuey has long tail also right?
