I noticed one of my older RIR hens hunched up and puffed out yesterday. Just standing in the run while everyone else ran around. Separated her out and tried giving her some scrambled egg with oatmeal (she ate a little bit) as well as water with oxytetracycline. I don't think she drank any of the water. This morning still alive but VERT weak. Just tried tubing her some of the mediated water with a little honey, but I'm afraid she's so weak I'm doubting she'll make it. After reading everything here I'm thinking Cocci. Sooooo, everyone else seems fine but should I get some Corid and treat the flock as a precaution? I have 28 chicks in two brooders. Should I treat them (3 weeks and 6 weeks)? We have finally started getting a decent amount of eggs a day after a cold winter, are the eggs safe with Corid treatment? Any help is appreciated.
