I have a problem with a 15 week old warren chicken who has a very runny nose and is sneezing a lot. I only bought her two days ago as part of a pair to integrate with my lone remaining ex-bat chicken. Because they are new they are separated at the end of the run and have a small rabbit hutch to sleep in at night which is bedded with straw and sawdust. The chicken who is showing signs of illness is ok in herself and has been eating and drinking, but this morning I noticed a clear discharge coming from her nose and she is sneezing a lot. She sneezed a couple of times yesterday but I didn't think much of it. I am just very worried as I lost two of my 3 ex-bats a month ago (1 to respiratory disease, 1 to peritonitis) and am therefore a bit paranoid. Could anyone offer some advice please. Thanks.
