I have 2 sebastopol goslings a little less then a week old. They where pretty clean at first but now are getting into their water. Someone posted about using a rabbit water bottle but I know they need to submerge their head(which they can't do in a chick waterer) so if I go the water bottle route how old do they have to be before I can give then a bowl or put them in the bath tub for a little bit once a day. I'm more worried about them getting chilled then anything. I'm open to any suggestions for waterers and swimming pools.
