This RIR chick is 10 weeks old and 2 days ago had a slightly swollen eye. This morning the side of her head is swollen and she is drooling. It is a thick milky substance. Her coop is brand new. The bedding is dry, pine shavings. The birds (total 15) have been in the coop for about a month. The bedding is about that old. The pictures should show the whole issue with her face. I am new to chickens this year, and could use the advice. Thanks.
