Sneezing Hen - An Allergy Maybe?

I have a hen who sneezes a lot in the afternoon/early evening. She's otherwise as normal and this has been going on for a while - it's as though she's allergic to something. Any ideas what we might do to help her?

Are her nostrils clear?

Hi Peaches and Clive, she may have a lower respiratory infection which is why she is sneezing/coughing, trying to clear her lungs (chickens have a very different respiratory system to humans). A trip to the vets for some antibiotics Tylan if possible, or Baytril will help. It shouldn't cost more than about £25 and ask the vet to listen to her air sacs, they will be able to detect any "rattle" quite easily and confirm diagnosis.
In the meantime make sure coop is dry and clean, disinfected and aired,no straw, just woodshavings for now.

Pellets are a good idea anyway, maybe dampen the mash for now to see if it makes any difference, but make sure it is changed everyday if you do that. It is good she is drinking if you have any Apple cider vinegar pop 25ml per litre and add a crushed garlic clove as well. Goof luck and keep us posted!

sorry I pop it in the water!
