So last night I noticed that my bsl pullet about 3-5 months old was super gurgly congested sounding, so I separated her away from everyone else, and gave her fresh water and feed. At the time her crop was empty. This morning she sounded the same and hadn't touched her feed put I saw her drink some water. This evening she sounds even worse and is breathing with an open mind and is lethargic and still hasn't eaten, I do have electrolytes but I won't be able to get any in her as they are at my school's show barn in my locker. I will be able to stop by the feed store tomorrow to grab meds for her if she's still alive, I just don't know what to get her. I really don't want to lose her as I went through alot to get her where she is now, and she is the 5th bird in my flock of 6 layers, one of which is a silkie who sounded a little raspy, but only barely. I will medicate the bsl by herself and treat the rest of the flock separately, just please advise me on what to get
