I  have two ex-batts I have had for 16 months  When I've let them out of the pen and in to the garden this evening, I have noticed one hen has been drinking almost non-stop from any water source she can find. 

There's plenty of shade in the run, in fact it's in the shade most of the day.  Her tail is a bit down and she is a bit subdued, but she seems ok otherwise and I've seen her eating. 

Any ideas what the problem could be?  Or has she just got dehydrated, and it takes a while for her to drink enough to re-hydrate?

she could be thirsty or she may have kidney problems

do you hang the feeders at a good height for them

[SusieB]

They have an Eglu Glug to drink from, maybe I need to go back to normal chicken water feeder.

could it be Gape worm ? they attach them selves to the inside of the throat !!!

have you wormed them recently ?

Doesn't,t sound good.  That is how my hen passed.  Tail down two days.  Drinking lots then dead on the third day.

Is her face looking darker or any blooming discharge on her face?
