So I was wondering about other peoples thoughts about NPIP testing. I was considering having it done this spring on the older hens and roosters that I have before my new batch of babies gets here this spring. Most of them are two years old or older and this year I lost two I am pretty sure was to the heat since they passed away when the temps were above 100 degrees and the humidity was super high. I lost one to laying a goose sized egg that was so large she couldn't fully pass it when I was at work so there was no one here to help her. Today I just lost my fourth bird a large gorgeous hen that had no symptoms of illness before today. She had just finished her moulting a few days before and so I am wondering if that combined with the -30 below temperatures outside were enough to just stress her out too much. I found her under the light in the coop away from everyone else. All my other hens seem very healthy other than that they are trying to finish up their 2 year old moult for those that are 2 and so some of them have bare spots and new feathers coming in in certain spots so they look a little bit fluffy rather than sleek and fully feathered like normal. But their eyes are bright and they are very healthy other than the moult at the worst of times. All these things together make me think that I should have the whole flock tested to make sure they are disease free. I had heard that the NPIP testing tests for the major illnesses that chickens get and if they are given the all clear then they can be certified as a healthy flock. I have a new batch of layers coming in sometime this spring or summer that is from a NPIP certified flock so I know that they will be healthy other than the stress from travel. Has anyone else done this and is there anything else I can do? I would love to hear thoughts from others as to if you had testing done and why or why not you had it done.
