About a week ago I posted a question about one of my barred rock chicks being very small. She is 3 weeks old now and is the size of a 2-3 day old and doesn't seem to be getting bigger. I see her eating and drinking and she acts normal. The chicks I got with her are at least 4 times her size. The responses I received were that maybe she is a dwarf/runt and will eventually catch up. I'm worried about her getting trampled by the other girls as they are so much bigger. Should I separate her from the rest? I hate to do this as I don't want her to be alone but I also don't want her getting injured. This is my first time raising chickens so any advice would be appreciated. Thanks!
