I live in Michigan and the weather here has been a little bit of everything (rain, snow, sunny & warm). I also used the deep litter method this winter. THis is my first winter with chickens. I now have a lady with gurgling noises. She has no other symptoms (eyes, nose etc) that i can tell. Would she maybe have caught a cold from using the deep litter method and this unpredictable weather we have had. Their coop has gotten kinda of gross from all the poo. I am going to clean out the coop without using any water right now as i don't want moisture to settle in just going to empty out all the used shreds and fill with clean. I kinda want to cull her so she doesn't pass anything on to the other ladies, but never have culled one before and kinda feel bad doing it without knowing what she has and also not willing to spend all kinds of money on meds. Would cleaning out the coop maybe help her to get better? Thanks for reading and any suggestions etc.
