I've lost two hens this week and one more looks sick. A necropsy was done today and the initial report is crop stasis and impaction. The only good news is that something contagious isn't going around my flock.
I'm hoping they will tell me what the impaction was, I'm guessing the grass hay I throw in the run to soak up all the mud after it rains. Which it did this week.
My questions, how can I help the one hen who is showing similar symptoms and what do you all use in your runs to keep them from being muddy messes?
Thanks for you advice and help.
@Purple House
I'm so sorry to hear about your losses

How is your hen?
Can you give us more information about the symptoms that she has?
Crop issues can be hard to treat.
If you suspect she has an impacted crop due to long grasses - isolate her so you can monitor her more closely. Provide her with plenty of water and a source of poultry grit (crushed granite). A stool softener like Ducolax may be helpful in breaking what's in there. You can find good directions in this article

Hopefully you will get more information from the necropsy. If they have not completed all their testing, ask them to run a fecal to check for worms and coccidiosis as well.
Crop issues can be a symptom of underlying conditions (reproductive disorders, worms, coccidiosis, infection, impacted gizzard, etc.) so it's good to know if there is something else going on besides ingesting long grasses/foreign objects. Since you have had a couple that died and another that is sick - it's most likely eating the grass.
Grass, hay, straw, leaves/pine needles are commonly used to add to wet runs to help dry them up and to give stable footing to chickens. Some chickens will eat some of these things. I always recommend to have purchased poultry grit available free choice, just toss some in the run or secure a little cup to a post - they will pick out what they want. Chickens
will usually find most of their grit in the soil, but I like to have it for them - a bag of grit will last for years (literally).
If you are unable to clear the impacted crop and your hen is declining and on her way out - you can try crop surgery to remove the long grass. It is best to seek vet care for this. I have never done it, but a few here on BYC have successfully performed surgery to save their girls. At home surgery is only done when all other treatment efforts have been exhausted and the hen is going to die anyway and they really have nothing to lose.
I'm very sorry - I wish I had better answers for you.
Keep us posted.
