Hello! I am new to owning chickens & new to posting on this forum although I've been reading here for a couple of months learning many things! Here is my question...I have a Salmon Faverolle pullet (hatched April 5th) that was bought from a hatchery & vaccinated for Mareks. She was one of 12 that I bought that week. I following week I purchased 15 EEs which were also vaccinated for Mareks. Everything has been great...no problems at all...until 2 nights ago. My daughter & I went out to close everyone in the coop & this pullet is laying kind of one her side/back flopping around. I picked her up & she felt a bit limp so I brought her in the house. She then stood up, started eating & drinking quite a bit. I decided to put her in a rubbermaid tote at night & keep her inside so I could keep an eye on her. She's been relatively quiet at night although once in awhile she will stand up, run around in a circle flapping her one wing & rolling her head around. The wing she's moving appears to be drooping more than the other one & quite often she preens that wing only...not the normal one. The wing doesn't appear broken or anything. During the day when the chickens are out in the run I will put her out there also to walk around. She walks ok (no limping or anything) but just isn't very active & that wing always droops down. When she's been in the run I haven't seen any of that weird circling behavior like when she's in the house. Through it all, she's been eating, drinking, & pooping like normal. I've been trying to look on the forum to see if anyone else has encountered this, but didn't find much on this issue. I did read a couple of symptoms of Mareks & was wondering if it sounded like it could be that. ALL of the chicks were vaccinated. A few other things I might mention...they are on an organic feed, starter grit, have fresh water daily, very clean coop & run & get fresh fruits, vegetables about every day. I am supposed to be picking up 7 Black Cooper Marans pullets-day old chicks (which will also be vaccinated for Mareks) on Monday & I'm wondering if it will be ok to do so. I guess I'm afraid if she does have Mareks what danger will the chicks be in? Hopefully I'm just worrying too much. Any thoughts on this would be greatly appreciated!
