Wednesday morning when I fed the chicks, I noticed the smallest one, a blue laced red Wyandotte seemed to have grown a ton in one day! But she also seemed very wobbly. They are on medicated chick starter/grower, on pine shavings, ina large enclosure, with a heat lamp in the corner. She’s eating and drinking fine, and poop looks normal. I have also given the same feed wet, and steel cut oats. No pasty butt, fresh water twice a day, grit is available. I started all of them yesterday afternoon on corid in the water, and they were all vaccinated for Mareks. She’s the same this morning. Any advice?
