Hi guys! I'm trying to figure out what's wrong with our male chicken. All 20 of the young flock seem to be healthy and active like normal. But this morning I found our Buff 10-week old lying on the ground acting like he couldn't stand right. So, I brought him to the house and checked him out. He doesn't seem sick or have any signs of a noticeable illness. But he has trouble standing, so he sits down mostly and drops his head to the side often. He was eating his starter & growth food really well, but he doesn't drink his water much now. We also noticed his breathing is really heavy and he opens his beak like he's gasping for air. Also, this morning my wife said his heart beat was going rather fast. We gave him some plain applesauce ( i read somewhere that mashed apples are good for any sick bird) and he seem to be doing better for a while. But this evening he looks so tired and his breathing is getting harder. Has anyone else had any problem like this before? Does anyone have any ideas what to do or clues what could have caused this?? We appreciate any help and advise. Thank you so much for your time. best wishes... Take care, Omran ...with help from wife Angie.
