*pic for attention. Our Australorp's hatched in the spring, we took six and my uncle took a batch as well. Uncle lives on a rural farm, and we live close to our major city. We have a big backyard with a ton of space, but just behind our yard runs a tram line with trains that pass on an average of every 30 minutes. Past the tram are some industrial buildings, then a larger train track with cargo horns going off more frequently lately, maybe 2-3 tines a day, and just beyond that is the constant hum of the major freeway. We also live a few miles from our local hospital with lifeflight that occationally flys by. My uncles hens from the same clutch have been producing eggs for a week now, and we haven't seen one. We introduced an older hen a little over a month ago and have only gotten one egg from her, and we also lost a bird to a racoon last month. My uncle has a rooster and we do not. I'm wondering if my birds are stressed from all the activity and it's keeping them from laying? Any thoughts?
