One of my 3 week old chicks is very congested sounding and sneezing. I’m thinking it is due to poor ventilation. The chicks are in a small bathroom and I’ve had the window closed because it’s been cold old (below freezing at night). I changed out all of their pine shavings yesterday and today she is rattling and sneezing and sounds like a human with a head cold and nasal congestion. Is there anything I can do for her?
