Hi All! I have a mixed batch of baby chicks and I've been somewhat active on here with them. I took this pic 2 days ago, and I was curious if anyone knew why my silver wyandotte chicks are SO much tinier than my buff orpington and new hampshire reds! They are a bit younger by a few days to maybe a week but I feel like they've barely grown at all. They seem healthy, active, eating, drinking, etc normally. Do wyandotte just grow slower?
