Hello I am new to this community and am a first time chicken raiser. I just bought four, 1 day old chicks a week ago, and put them in a box with a heat lamp, bedding, and food and water. Everything was going well until I noticed one of my chicks, the biggest actually, was not acting like her usual self. All she wants to do is sleep. When the other chicks play, she sleeps. She sleeps mostly standing up, then nods off and wakes herself up. She wasnt eating drinking or pooping either. I researched a bit and decided her symptoms seemed similar to symptoms of Cocci. I went and bought Corvid immediately, and put some in the chicks water. I also took a small syringe and gave her some of the medication through that. I did this twice, and the second time when i put her back in her cage she ate a bit. The problem though is that when she ate she seemed like she was having a hard time swallowing and kept opening and closing her mouth for a bit. Then she went back to sleep. I am planning to give her more Corvid water in the morning, but should I be concerned about the swallowing? I am new to all this and dont know what to do. Please help and give any advice if you can.
