Yesterday I noticed one of our Buff Silkies not acting right. She just wasn't as active as she should be. She is 5 months old right now and we have 2 other bantams that are the same age that came with her. This morning when I went to let them out to free range she did not move to come out. After a few minutes I climbed in and got her. I keep the coop very clean the water is clean and so is the food and I clean the poop out daily. Since having her inside (brought her in around 6:30am) she has basically just been sleeping. I have gotten her to drink a little by putting her beak in some water but she won't eat not even treats. She has sneezed a few times and I know she can move. I took her in to wipe some poo she had stuck to her feathers off and she was walking on the bathroom counter. She will clauk every so often and look around but pretty much stays in the same spot I have her on the living room floor on a spread out towel since she's not moving much. I also have food, treats, and water out for her. I have called almost all the vets in an hour and a half radius non will look at her. No one seems to have experience with chickens most people here don't keep them as pets. I have also looked for Tylan 50 no one around has it. I suppose I could order online just affraid it won't get here in time and may not work. I have no clue what she had she is my first sick bird and sadly she is one of my favorites that I have bonded with. I don't want her to suffer. How long do I wait before making the judgement call to have her put to sleep. A vet will do that for me just not try and treat her. I can't do it myself it would kill me to do that. Please help I have no clue what to do.
