Hey, So right now I am brooding my first batch of chickens since I was a little girl. We right now have 18 chickens of various breeds, with about 5 being a week + 3 days and the rest 3 days old. They are being raised in a converted reptile cage with wood flooring, topping and sides minus the front which is covered in a fine wire to allow air flow. There are two lamps stationed 1.5 feet from the ground, one with a 250 w bulb and the other a 150 w bulb. (It gets very hot in SC right now so we have to alternative usage depending on how they are acting.) The cage litter is straw. I got a Columbia Rock X RIR cross from Tractor supply Co a few days ago. After putting her in the cage she alone developed a cough. A day later she has fluidy sounding lungs...we sent her back and got a new one who was isolated until we heard the results of the vet looking at the chick. Vet said she was fine so we tossed the new one in with the others. She started drinking from the water...and drinking...and drinking. I had found a small red, lid from the kitchen to give her water with when she was alone. The big 1 gallon is the pretty standard type you see at feed stores. The tractor supply co was using more of a dish thing though. Then she started coughing. After searching the web, I put small rocks in the water to prevent big gulps. But she still has the cough. She's very active. In fact the biggest. (We have 4 buff orps and 1 silver wyandotte of the same age). She's a good forager and has no other problems. No treatment has been given yet. Thoughts?
