My hens are approximately 18 to 19 weeks old as of March 14, 2023. This breed is to start laying about 22-24 weeks old. Approximately two weeks ago one of my girls started acting like she didn't want to be around the others. A couple of those days out of the two weeks she did not even wanna come down out of the coop. She is still getting food and water. But she just wants to sit on the ground. And a couple of times I noticed when she went to get up and walk she wobbled a little bit, not constantly but just when she first would get up, a couple of times. I have no clue what to do. I did put electrolytes, vitamins, Apple cider vinegar and some Corid in their water about a week ago. I just wanted to wait and see how that affected her and it didn't seem to help much. I have picked her up a few times to take her out of the coop and put her down in the run where all the water and food is and she felt very light and thin. Please help!
