Hello, our 7 month old Ameraucana started with a little sneeze about 5 days ago. She also sounds a lil funny when she is clucking in her pen... I started her on the vet Rx and it seemed to help, but just a little. Yesterday she started having very watery poop. I'm not sure what to do. I have Tylan 50 should I start her on that and if so how much and for how long??? We are new to chickens and she has become our absolute favorite... I hate that she isn't well. Any help is greatly appreciated!!
