We just gave our 6 week old chicks fresh water and shortly after, my wife noticed one was tipping her head back and it looked like she was chewing. I grabbed her and checked her and she had foam in her throat and it started coming out her mouth. She kept her head back and continued her chewing motion and kept foaming. I held her head down and rubbed her chest and wiped the foam out her her mouth and throat. Could she have aspirated some water? And if so, how can I help her? If not, what could be wrong. She was acting perfectly fine until now....
