[smelly]

Hello

Could anyone help me, or am i worrying to much.   4 of my 6 back garden chickens have just recently started to sneeze and cough.  They seem ok in every other way, they are eating drinking well i get between 4 6 eggs everyday so no worries there but they seems really blocked up like they have a cold.  Should I worry or get any medication or just see if they come through it.  I live in spain and the weather has just turned a little colder.

Many thanks

colder weather shouldn't be a problem, I would get them checked by a vet if possible, might be a viral problem

The odd sneeze (I mean the odd every ten to 20 mins) is OK. 
Coughing is different.

If they are "really blocked up" you will need to take them to the vets they may have Mycoplasma.
