We got all these chicks 3 weeks ago on Friday and they're all doing really well. However one of them is still absolutely tiny. It's eating and drinking but it also stays in the corner out of the way more but every time we are worried about it not eating we will see it head over and eat/drink then go back to it's corner. Putting a picture below to see the size difference, they were all bought at the same time and were all the same size when we got them.
