Ugh. Pleeeeeeease help! I have 3 hens who are about 16 months old. They're never loose in the yard - they have an enclosed run and a moveable chicken tractor to access grass. This morning I noticed that my BR has black worty spots on her comb and wattles. I searched BYC and it looks like Avian Pox. The other two hens (EE and BO) don't seem to be infected - or if they are, their combs and wattles are clean. Should I separate the "infected" one? I have a separate run, but not a separate coop for nighttime safety, although i do have a small cage (my little broody buster cage) that I could put her in on our patio at night.
Thoughts?
Should I be treating this with anything? Do I do nothing, leave all 3 together, and just let it run its course?
Advice on what to do with other 2 birds? Or is there a way I can see if they are infected?
I'm a total novice on chicken illnesses and want to do what i can for my girls.... I'm so stressed for her...
Also - can it be transmitted via mosquitos? Or is this something they get from other birds?
Thanks in advance!!!! I feel totally lost and don't want to miss doing something I should be doing - thx!
