Check her condition at the breast to know whether she's losing weight. The keel bone should not be overly prominent and this is always best to check against a known healthy bird of the same body type as it's a bit of a sliding scale. Heavy production light breeds will have a more prominent keel and less muscled than a heavy breed hen.I'm sure they are stressed about being in the small covered run. They usually have about 1,000 square feet with plants and a boulder they like to climb on! We've been wanting to build a new coop with a bigger covered run, but got discouraged about the chicken ordinance where we live. We need a variance to put it anywhere that isn't directly out our back door (basically where our back porch is!) and it's...a process. I've been trying to figure out something temporary within constraints of the budget and rodent pressure so it needs to be rat-proof.
She hasn't molted yet and her feathers look AWFUL. I was giving them a bit of veg in a peck toy for forage/enrichment, but it sounds like maybe I should give that a break while figuring this out because it's not as nutritious? Honestly, I'm not sure how much she's eating. I brought her inside about an hour ago for a snack and her crop was empty, though I've checked at other times to find it full. I think I need to bring her in for snacks multiple times a day while I work on this.
Thanks for your input!
