Hey guys, Just started the lovely forums, cause I was giving my grey a shower. I already have a timneh, he is 32 and he tooks normal showers from a showerhead, and I bought another grey, he is 20, and he seemed to enjoy the shower as well, he walked under the water and just sang away, but I have some worries, after his shower he had a huge bulge in his neck, and it looked as if it was filled with water. My new grey(spike) has a bent beak, SO it has huge gaps on the sides, do you think water filled his neck sack? It does look like water is in it, he doesnt seemed bothered by it, just taking very watery poops alot. Thanks, for any and all advice C
