Hi, thanks again for your help and advice. The roosts are there or there abouts between 15-18" and whilst there is additional shelving left in there from the previous owners its very rare that any of them use it, however have taken all that down today - just to be sure. Having never had a case in 4 years, 2 together on the same day is - well, its just chickens I guess. They're still quite happy, eating and drinking and have bathed and cleaned and have latherd everything that's not featherd with antisceptic spray and cream with t-tree, aloe and witch hazel.
If they're not considerably better first thing tomorrow then will be a double lancing - have only just got my mare right from a series of tooth absess and my gelding from a punctured sole so a little chicken surgery and a good old fashioned flushing isn't an issue, although it is, somewhat on a smaller scale!! Will let you know how it goes. I'm guessing that it won't be pretty with infection and blood, would that be normal?
Thank you, all, again for taking the time to comment.
Kindest regards. Nicki x
