We've raised 3 day old chicks to the point where they're starting to lay with LOTS of help from a local organic farmer and this forum! We started with 8 chicks from Tractor Supply that are supposedly from "a hatchery in Arizona" that were in the "mixed dual purpose" bin, and 12 from our friend who purchased hundreds from a more local hatchery. The Tractor Supply girls are 4 reds (who were the first to start laying), and there are 4 barred black ones that I can't for the life of me tell apart from the 2 that I got from our friend that are supposed to be Cuckoo Marans. IS there a way to tell these girls apart? They haven't all developed their combs yet. I don't NEED to tell them apart, but I'd like to. We lost one to a predator, but the rest of the flock is: 3 Silver Laced Wyandottes, 4 Columbian Wyandottes, 2 Ameracauna (or Easter Eggers???), and a Cuckoo Maran roo. Thanks for any thoughts you can share!
