This is my first time raising chickens. I have 2 BOs almost 4 weeks old and 4 silkies from 2-4 weeks old. I saw some red poop and odd behavior so after some research I treated the whole gang for cocci using Corid. It's been 5 days, I'm about to reduce their dose to the smallest amount because most are doing good but one is still having funky poos. Anyways, the 2 that I suspect had it or at least had it the worst (1 BO, braveheart, and 1 white silkie, Bowie) are considerably smaller, and a little bonier than their brothers and sisters who were born at the same time. I think that they are going to be ok, they are running around, eating, drinking and being normal but now I am wondering about their future. Are they always going to be smaller? Or will they catch up? Will they be happy and healthy and produce eggs like the others? New chicken mom here and I love them to death already thanks for your help!! PS: love the coop posts, im building one inspired by a couple from this site this weekend!
