How to avoid my hens dying... again

Depending on your available space, you could try moving / building a new run on a different side and painting the coop inside and out. Or trying a completely different area of your property. If you're on a well, you might look into having your water tested for pathogens.

@BarnyardChaos now you made me curious! Would soil with natural limestone be more resistant to parasites?

I have no idea

Hi all.

I've only done one previous post on this site, and that was 28th April when I thought I had cracked my problem.

My last remaining hen, a large Buff Orpington called Buffy, died last week and I'm quite upset. I had rescued her from the brink in April by finding and treating Capillaria worms with fenbendazole. She was happy and laying again for a month. She then took a downward slide again, she first got broody, then shortly after started to be less active and developed a limp in her right leg- foot and leg seemed fine on checking, no infections. Around this time I noticed vent feathers were dirty so cleaned her and treated her again for worms, which it was recommended to do anyway at this time point. No change. She started to eat less, eventually eating almost nothing at all, all day, perhaps pecking at some grass and eating one or two mealworms. She barely pooed, but pretty sure she wasn't egg bound as this dragged on for weeks. She rapidly got weaker last weekend and died. These were her only symptoms, no respiratory problems, no signs of gleet or lice.

Me and my wife are now quite put off keeping hens, as that's our third of our first three and they all died in similar circumstances (although spread out over 12 months).

We're even convinced the coop or run itself is causing the issue, as the previous owner of the house itself said their hens died of unknown illnesses in the same coop. We cleaned it thoroughly before we used it, but kept the run the same.

So my question- Can anyone out there please tell me of any environmental issues that may have contributed? Can worms or other such infectious things persist in the soil of a run? In which case, how can we start again knowing we've done everything we can to stop the same things happening? I've heard of people 'treating' a run or a house to really clear up for a new set of hens.

Sorry its not a lot to go on.

I have lost 7 chickens one at a time over about a year or so, with very similar symtoms .About 3 months ago I got 6 additional Australorps hens most 3 -5 months old, kept in a separate coop, run and yard and all were very healthy. now they are getting sick,one has died.One thing that caught my attention is the limping, the first one to have any noticeable effects was limping,I thought it had injured itself.I put Chlorine dioxide in the water and she bounced back but then it came back and she slowly quit eating and died.Then another one is limping even worse and her lookalike friend stays right by her side and now has a grayish growth over one eye and across her beak
