One chick is tiny compared to the others

I also have that exact problem... but i don't know why.
It could be she hatched out of a small egg, or just a runt... sorry i couldn't be more helpful.

Could be a runt, could be failure to thrive. As long as it's eating and drinking then it's just a matter of wait and see.

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.

I have the same issue and her toes on one foot began to curl. I put Poultry Cell in the water for the last 2 days but will start a direct oral approach tomorrow because I don’t think she’s getting enough in the water. Going to blast her with vitamins! I also separated her from the others. My girl is about 2 months old now and I’m worried it may be too late.

Wish I could help. I have the same thing from chicks I hatched. One is half the size of most of the others. Even it's "siblings" from the same hen that laid the eggs it is much smaller. No clue why. Mine are 4.5 weeks. Mine also stands around a lot and calls for the others as they are running around. Here is it next to one of the bigger ones it hatched with and also one next to a sibling.

Looks great though. Feathering nicely, perky. Def not a failure to thrive, appears quite the opposite.

Any chance you have a smaller chick you can put her with?

Little bit of a necro here but I think we figured out what was going on. This chicken has developed a pretty serious looking cross beak and the internet suggests that would cause her to be smaller since she has a harder time eating. We have been wetting some food for them recently and she gets after it pretty good on the wet food. Attaching some pictures to show the beak now.

Since the rest of them are growing fine I'm going to chalk the issue up to an injury when we bought her or something along those lines.

Problem solved! Good for you accommodating here and the cross beak doesn't look too serious. She should be able to have a good life with minimal accommodations once she grows a bit.

I have the same thing with one of my legbars! I cannot find an answer as to why she is so tiny! She is having balance issues. But other than that she is fine. I have her separated to give her extra rest and vitamin.
