We have a hen we don't know her age shes a lafeverlle I know I spelled that wrong but hopefully someone will know her breed. Anyway she is usually very vocal and always wants out of the coop first, but this week its been very cold we live in upstate new York and she isn't coming out of the coop and not vocal at all. since the water is outside in the run im concerned that shes not drinking wateror eating and shes making a funny unusual sound. im very worried about her and her having a viral infection. Does anyone have any ideas what could be?
