Hello. One other question I forgot to ask was about them bathing. My cockatiel I had when I was growing up would take a bath in her water bowl. I never see my 2 near the water bowl. Are they drinking at night while I sleep and will they try to bath that way? If so do they not bath during certain seasons?. I know it's winter so I would expect not. Wondered if I should be misting them. They are very active and healthy birds, just never see them drinking. Any help would be greatly appreciated.
