This is going to be long THree (or four? ) weeks ago I posted about a lethargic pullet, she didn't have anything particular wrong with her, just fluffed up and looking depressed. I did bring her in and made sure she was eating and drinking after 4 days I put her back in the coop. I have chicks inside and I didn't want them exposing each other, and since she was already with the older birds.... She has continued to act the same. except now she is clumsy and very skinny and last night she was tripping and falling and walking in tight circles. Now a couple of my other birds are looking clumsy, they aren't fluffed up or pale looking like she is, but i'm noticing that they trip alot. now the history. they are 14 weeks in with two 16 week bantams. We have never had chickens before, we got the bantams from another breeder at about a week old, they were Vaccinated for Mareks. the 14 weekers were not I hatched them myself. I think my bantams with the vaccine infected my flock? Is that possible? And how long does it take for the Mareks to spread? the first pullet has been ill for almost a month, and in that time I never saw symptoms in the other birds, now some of their feet look reddened on the bottom. Help!
