I have paper towel on top of deep (6 inches) of pine shavings right now and the 24 chickies are a week & one day old now, they peck at it around the edges of the paper towel, are they ready for just bedding (getting rid of the paper towel) yet? One other question, are they needing a perch yet? I've raised their feed up and they like to sit on top of their chick feeder and have been pooping in it (maybe I need to put vaseline on the top LOL.) If they do need a perch how high up do you usually put it and what "specifications" should it meet (length, width, material)...Okay ONE more, when can they have treats??
