Hi, my Araucana is sick. She's sneezing and wheezing. None of the others are sick. Should I seperate them? It's getting cold outside here (Northern WI) but we have a heat lamp in the upper part of their coop and their windows have plastic on them. She's making very sad little noises. Not sure what to do or where to take her? She's about 8 months old. Any help with this would be great! (To make matters worse, she's my favorite girl!) Thanks in advance!
