She didn't make the night. And this morning her 3 flock mates are all feeling bad. I brought them inside and gave them corrid water, yogurt and crumbles. Came home a couple hours later and one had already died. The other two are mostly sleeping under the heat lamp but will drink every time they wake each other up and they are chirping so hopefully they'll pull through. They are our favorite... the legbar we hatched and the BLRW. I can see them from where I sit and they are both drinking right now.
They were already sharing the same space, just not sleeping together so I wasn't worried about integrating them. Whatever it is they have all been exposed to it. I think it was just that these 4 are a couple weeks younger and we've had a couple cold nights suddenly. I think it lowered their immune system enough they couldn't fight this off like the bigger girls could. No one else outside is showing any symptoms. But I'm keeping them all on corrid just in case.
