<my mom has a cokatale(sp?) named joey. he is all white andhas a yellow head. as a bird...he isn't very well coardinated. he falls off of pearches so often its amazing he isn't dead... he also seems to take his time from getting around the cage(I think he is scared of falling o_o)

anyway...the other day, joey was just standing on the bottom of the cage, right in the center doig nothing at all. usually he is either eating are gaurding those eggs they have from my dad.(>_>;) but not this time. it was like he had no desire to do a thing. he wouldn't eat or drink water. his cherps...usually loud...are now a tiny squeek. even when he bites your finger...he is usually quite strong...but not now. my dad took him ou of his cage to check him and the feathers around his rear end are all green. he eats now but just very little, and noting big. he hasn't drunk water(from what i've seen). whats wrog wit him?

Zoey, the grey and whte one is perfectly fine.(to be honest, she is the exact opposit of joey) she climbs the cage so fast its unbelievable. she jumps from one end to the other with no probem. She also has a mean streak and will attack anyone that gets near her(except joey). when she bites she bites to rip off your nail or skin. and she is in perfect health. they are kinda funny cause joey is usually well behaved and zoey is so aggressive. but yea....I just want to know...what is wrong with joey? (btw, we had them from around 3 or 4 years)
