I am a newbie to this, we have always had older chickens never chicks. We got 6 baby chicks on Sunday, so about 4 days ago and they were about 5 days old when we got them. We have them in a big cage with pine shavings. They are in the house and the smell is horrible. What do you all do about the smell? Also a couple of them have pasty butt and I am having to clean their bums everyday. Is this normal? Is there an age when they out grow this issue?
