I'm a new chicken-mom, with 7 babies (2 RIRs, 2 gold sex-links, 2 Wyandottes, and one black australorpe). The chickens all seem healthy and happy, about a month old (I'm not sure how old they were when we got them). They were all the same size when we brought them home, but now the wyandottes are significantly smaller, and are not getting their feathers as quickly as the others. I thought maybe it was a breed thing, but I have noticed that those two do not spend as much time at the feeder as the others, and I have seen them scratching in the pine shavings more, and then they peck at them, and if you look closely you can see that they are actually eating the smaller bits. Is this normal behavior? Could this be why they aren't growing as fast?
