We have 4 Dominique chicks that are 5 weeks old. I know there is variation, but one of them is much smaller than the others. Her wings and feathers are different also. She seems spunky, but she is so small. Should we try to feed her anything different to help her catch up? In the picture she is the one on the left. We have buffs, Wyandottes, and Australorps (2 of each) and all of them look gigantic next to Tiny. I added a second photo with a Dominique, Tiny, and a Buff (l to r).
