Is this normal? She is the only one looking like this. When I picked her up, other feathers fell out. What do I need to do? She is about 3 years old, live in Texas and it has been very hot. I think it is done raining for the summer. I have one drake her age and 4 other hens that are about 1 year old. Then there are 5 that are 3 months old not sure what sex they are yet. They have a pond in the coop yard and lots of shade. Plenty of water and I have one water bowl with apple cider vinegar, they get chicken layer pellets, grit and oyster shell. I clean water bowls twice a day. Is this molting? Never seen it quite like this. Thanks for any help.
