These two chicks in the picture are 3 days old. They came from Paris Farmers Union who gets their chicks from Murray McMurray. They are supposed to be an assorted mix of "heavy breeds" for meat, all cockerels. The woman at the store thought the yellow one was a Buff Orpington and the chestnut/yellow one a New Hampshire. Honestly, I know she didn't have a clue as she told me the barred rock (or male black sex link??) chicks were male golden laced wyandottes! Ummm, OK. I knew they weren't but it didn't really matter. I just thought the little chestnut with yellow guys were sooo cute! Very pretty little fellows. Here's what they look like at 17 days old: These are the ones that used to look chestnut with the yellow wings. This is the one that was all yellow in the 3 day old picture. He is 17 days old here. Here's the 17 day old yellow chicks from above. EDIT - because I messed up in one of my replies farther down - all of these do have SINGLE combs, no wyandotte type comb anywhere to be found. LOL.
