I'm not sure if we still have the box but I'll check and let you know. The chicks are SO friendly! Especially the Jersey Giant, Buff Orpington and the Silver Laced Wyandotte. They compete to climb into my hands! The others are friendly too, just not so in your face about it. LOLHey that is the exact same box setup / straw and top we got our chicks in-- ours came from (California Hatchery) I know MPC sources chicks from other Hatcheries-- ours were really good too-- the hatch time and date should be right on top next to the postage stickers-- I would be curious to see if they came from California Hatchery?....
