My hens are almost laying age...I was told they would lay in about a week from now. I have had them for 2 weeks. They have been acting normal, except today one of my RIR is walking slower, kinda awkward, hunched/puffed up, and her color seems to be lighter. She is not hanging out with the others as much and tends to stay in one spot longer. She is the larger of the 2 RIR that I have. She squatted once when I went up to her and petted her, and she let me pick her up which none of them are doing yet. I also show how she is puffed up. I pulled her tail feathers back to see if I could see anything odd, but I don't know what Im looking for. Is she sick or getting ready to lay? When I throw feed in, she goes crazy and runs up to me like the others do, so shes not hurt that I can tell. Thank you.
