So I have two English Orpington Chicks (3 weeks old). One is a porker. I think she thinks she is a meat bird. She is ROUND. She is heavier (rounder but shorter) than my Barred Rock and Gold Sex Link who are a few days older and way further along in development. I don't notice her eating more than the other chicks and she is quite active but I do notice she does things like lie down to eat (not always - just sometimes). Is this something I need to be concerned about - or can we just keep laughing?
