Hello everyone! I am a brand new member (I just joined today), and a new hen mother. I have a 7 month old that I bought from TSC. .She has always been the smallest and the lightest, but lately she seems quite a bit lighter. This morning when I let her out I saw that she had no feathers from her vent down about 4 inches and the feathers near her tail feathers were all messed up. My girls have been healthy except for a sour crop (not her), and this is making me sick with worry. Hubby & I checked her and didn't see anything moving and no nests like I saw online. I live in northwestern New Jersey and I worry about her freezing when she's outside. Please help me, they're just like my children to me and I love them. Thank you so much for your help.
