before now I've never had a problem with pasty butt. but I've lost two babies to it so far...not sure whats going on but only change was with my shipped chicks I gave them brown sugar water when they first arrived then switched it out with fresh water. they get the same chick starter I've fed all my babies and this is the first time I've had losses over it. So Q-tip and Olive oil, hard boiled egg and lowered the heat lamp again. I added some electrolytes to their water hoping that will help. only change with this batch was the brown sugar water...I won't be doing that again.
