I've had the chicks since Thursday evening (hatchery mailed them Tuesday, postal service bounced the box of them all over the US) and I know they had plenty of stress during shipping/travel. I took care of pasty butt twice yesterday and have done it once today so far. How long before it will start clearing up? I have warm water for their drinking water, room temp and no colder than that (room temp is 78, temp over the chicks is 95-98, but they have lots of space to move from the heat if they want) and the electrolyte solution that I ordered from the hatchery is in their drinking water. Medicated chick starter feed is in there, as much as they want. They are on pine shavings for bedding. I change their water several times a day and check food. For heat I am using the red heat bulb that is supposed to be used for chicks, with the standard poultry reflector to put the bulb into.
