I locked up the chickens tonight and noticed a noise... if anyone had heard someone wheezing from asthma... you know what I'm talking about. Just one though, I have had them for 6 weeks on our new property no new birds no used waters/feeders.... everything brand new. What would make one lone bird wheeze like this? It's 10:30 and I'm going to go back out to the hen house and put her in the garage as I don't want to even think about what would happen if these birds came down with something. They came from Moyers hatchery as started pullets so something very well could be in these birds.... just laying dormant.... but I highly doubt it. They have been free ranging on pasture since the day I picked them up so no sudden changes to them since 6 weeks ago. With my experiences it's either CRD... or something in her windpipe? I'm going out to get her to put her in the garage as like I stated... I just can't take the risk.... any input? ETA: There is 113 birds all from the same place.... only one wheezing.
