On Wednesday I picked up an OE bantam pullet from the state fair. (I only got one because I need a friend for my blind RIR bantam). We got home late and when I put her in her makeshift coop I thought I heard a couple clicks as she was settling in. Yesterday morning when I went to check on her she had her head tucked under her wing (none of my other hens sleep like that so I'm not sure how weird that is) and looked fluffed up and unhappy and I heard what sounded like a rattle when she was breathing, but I had to leave for work. When I got home yesterday she was very clearly rattling when she breathed, so I gave her a dose of Tylan and moved her into the bathroom with a heating pad available for snuggling if needed. By bedtime she was occasionally gasping for air and she woke me up this morning making crazy noises that sounded like a cat's meow or maybe a chihuahua bark. She was gasping more frequently and "barking" every few minutes. She seems to be happiest on the heating pad (it's not too hot) and I did manage to get a few drops of electrolyte water down her throat before leaving, but does this sound like IB or something else? Is there anything I can do to make her more comfortable? Thanks guys!
