I've been using Broiler Booster, 1/2 tsp/gal of water, since I got my 16 chicks. Yesterday, I had to clean off 2 of them's butts, today I'm already seeing 1 w/ a smudge back there. How does a hen handle this? I ground up oatmeal for them, but now I wonder how much of it they should get. I have been using a sprinkle of baby grit on their food every so often and have given them scrambled egg (both suggested by Murray Mc.). I have to work, so I"m out the door soon and won't be watching them (dh watches, but his health isn't good and I don't think he'd do more than call me if something happened). When I washed the 2, I forgot about the oil/vaseline, but those 2 look okay this morning. Should I do anything more than what I'm already doing? Their area is 6' by 8' with half of it sheltered w/ heat lamp and the other half open to the outdoors, so overheating shouldn't be the issue.
