with it being alencon all birds in the baskets have experience of an overnight stay or two and know how to get a drink. as most of us know our birds are very well looked after when in transport by the s.n.f.c. as it has been pointed out all the drinkers look to clean. the conveyor would have emptied the drinkers and put fresh water in then before he took the photo. the reason i am thinking this is 1 he would want the photo to look good and clean.2 if birds had just had them put on then their would have been a dam site more than 3or4 heads in the drinkers.another reason for changing the water before photo is you can see a bird with butt sticking out and just like our drinkers in loft they will get sh1t in. as for me i am happy with the way birds are looked after and glad to see the photos look forward to seeing more
