the last 2 weeks it has been raining non stop here in northern ontario so my chickens haven't really been out much. Yesterday though I went in to give them a bit of scratch before calling it a night and noticed a couple of the chickens acting funny, they are only 15 weeks old, but they are kinda squatting and then lifting their wings, walk a couple steps and squat again, and they are super talkative too, but not the regular chicken squabble but long complaining squaks. today I went in there and a few seem agitated. the coop is an in barn coop. I checked it all out and there is nothing there, but I did notice that all the corners the hay and shavings were all turned up into a big round pile like a nest. My girls have nesting boxes made of milk crates,, with shavings and hay but I don't think they like them. Is this behaviour of their laying behaviour or could they just be irritated they can't go outside. I am afraid to let them out when its raining cause its been super heavy rain!!
