Hi, i recently got 2 new chicks (one maran, one black silkie) and the maran is sneezing a lot. She is about 4 weeks old. I guess she's been sneezing a little bit for a while, but today it's getting really bad. She has a very wet sneeze, and is making loud watery bubbling sounds when she breathes. sometimes she walks around with her beak open, like she's trying to get air. What is wrong with her? is it just a cold? I din't see any other symptoms except she might be a bit more tired. Help please!
