I just got 13 new chicks. I got 6 from TSC and 7 from a local place that ordered from McMurrays (small hardware store taking orders for us that live rurally so we can split shipping cost). I got 6 from TSC last year and 4 locally not a single problem Anyway 2 of the ones I got locally have poop drippings on their bottoms. Not blocking the vent just like it caught in mid fall. They are happy and running around all other are fine and healthy. These guys are 4 days old. Is it pasty butt or just dirty chicks? I cleaned them regardless just wondering if I should keep a closer eye on them.
