I'm a new chicken owner and have 4 different breeds about 9 weeks old. All were feed store purchased and supposed to be sexed at the hatchery but there is always human error so I just want to make sure I'll be able to keep all 4. The one is a black sex link so I'm pretty sure I'm safe there as it was all black as a chick, I've done a ton of research since we got them as chicks and I'm pretty sure the rest are all female as well but I'm new so I'd like a more expert opinion. Thanks!
