An extremely sad follow up to what I thought was a happy ending to this story...
When I took this hen to the vet several weeks ago, the vet felt her crop and said it didn't feel impacted and that there must something else going on. I told her I had lost three hens this spring, to what I thought was reproductive tract complications from infectious bronchitis - as the flock was sneezing at the time. The vet mentioned Mareks but I had seen no neurological or eye or skin issues in the flock, just sneezing combined with watery albumens and then soft-shelled/shell-less eggs and the loss of these three hens over the course of 2-3 months, with the last one dying in July. My flock is all vaccinated, so I thought there were safe from Mareks - though the vet corrected that misperception.
And I thought I had figured out the something else for this hen when her crop improved following the Safeguard treatment...
Then, this Saturday, when my hubby and I were deworming the rest of our flock (despite finally getting fecal float results that showed low levels of coccidia and nothing else) - we both noticed this same little hen standing still, puffed up, and shivering. In the afternoon, I saw her neck kind of spasm backwards and she staggered a bit - and my heart fell into my stomach. This was the first indication of neurological issues in my flock.
I have now read the long Mareks post, and some pieces have fallen into place ... as my heart has broken into a thousand pieces.
Apart from this one hen, I have had the rest of my flock of 9 for over four years, and they are beloved pets. Two of my favourites are 'off' in addition to the visibly symptomatic hen. Looking back, as they headed into molt this fall I noticed some slight blue tinge to a couple of combs, but thought it was just the molt or the light, and my lead hen's crop has just looked loose for several weeks, but never impacted. She had a couple of very mild neck spasms today, and the other hen that isn't doing well had what seemed like an impaction way up in her neck - where I read somewhere in the last two days that Marek's issues can show up.
I will probably start another *Mareks* thread about what to do for my flock but thought I'd start with the follow up here ... and ask a few questions:
- if some of my flock are not showing symptoms, how much of a difference will it make for me to cull the symptomatic ones - especially the hen showing the nerve symptoms? (I fully understand they are all infected)
- I've been giving vitamins in their water the last 2 days - what else can I do to support the flock?
- what are the chances of remission, if a chicken has started showing neurological symptoms? I thought I read one post where someone talked about having built ramps for their hens who survived but couldn't walk very well, but I thought I read elsewhere that once they start showing neurological symptoms, they are pretty much guaranteed to die
- should I treat for coccidiosis, even though the float didn't show concerning levels? could this help support immune function?
We have already spent over $250 on this hen and I don't think I can afford the shipping plus the lab costs to get her tested. Her nerve symptoms seem far worse in the morning and I will try to get a video of her tomorrow. For much of the day, she has bee foraging fairly happily with the flock. She can't make it onto the roost anymore, or is falling off, so I have been tucking her into one of the nesting boxes at night. I just have this pretty clear feeling in my gut that Mareks is what we are dealing with. My vet mentioned it is incredibly common, which I'll admit I had zero awareness of despite having spent more nights than I can count reading posts on this site.
This will probably spell the end of chicken keeping for me. I had no idea it could turn out this horribly, with the entire flock dying slowly of a virus with such awful impacts. I have no idea how this came into my flock as we have had no visitors to our chickens this year, I keep a pretty clean coop, I have only ever brought vaccinated chicks and pullets in, and have not brought any new birds in since the fall of 2021. Yet, here we are.
