So I may have made a bad choice when I bought chicks this spring. New Country Organics feed store is nearby and they were offering a few different breeds of day old chicks in February. I have no idea what hatchery they came from. I know-bad idea, right? But, in the fall I ordered 7 day old chicks from My Pet Chicken and had a terrible experience. I spent over $100, only to have 1 die the day after she arrived and 2 turn out to be roosters. So, I only have 4 laying hens and we really wanted about 6-8. Unfortunately, getting small orders of chicks from the well known hatcheries is either impossible or very expensive. The local store let me order 4 day old sexed chicks for the bargain price of $14. Now they are almost 4 weeks old. 2 are supposed to be welsummer females and 2 "ameraucanas," but they are really EEs. One of them is TINY. She is less than half the size of the other 3. I think she is an EE, but honestly the breeds look so similar that I'm not entirely sure. She was always smaller than the other 3, but only by a little bit when we first got the chicks. Now it is like I have a 1 wk old chick in with 4 wk old chicks. She appears healthy, eats/drinks normally, seems to be getting her feathers at about the same rate or just a bit slower than the others. She does not have any deformities and no injuries from the bigger chicks. They don't seem to treat her any differently. Are chicken "runts" a thing? Is she a bantam? Is this anything to be worried about?
