ok maybe a few more... chicks are now 3 days old (1 day at home). 1. can you make any inferences about chick markings and feathering later on? I have EEs that I'm asking about... 2. they are discovering pine shavings under the toweling, and I'm just watching them, should I stop them or just let them get pre-exposed to the shavings (was planning only on another day or so before they are on them anyway) 3. one has a sort of foamy looking poo, but otherwise seems good, is this ok? and lastly 4. some minor pecking going on, but I figure they are just sorting themselves out... can they hurt each other at this point? thanks!
