I think I messed up and posted this without it actually being a reply. Sorry. Still learning this platform.
Here was my post: She weighs around 3kg, which I know is within the normal range. BUT… while her keel feels ok, what we learned in losing the other girl (a Buff Orpington) is that keel feel is no longer a good indictator of body condition because domestic chickens just don’t fly much. There are better places (inside thigh, low abdomen near the vent, and under the crop) that are better indicators of being overweight and at risk for fatty liver. When we lost our Buff, we were able to get her to the vet within 15 min of her collapsing. They did everything they could but she just couldn’t be saved. We had them do a necropsy, so the diagnosis is indisputable. The vet (and these are exotic animal, including chicken, specialists) said she would not have considered our Buff overweight because it was not evident in her keel. So she reached out to an avian specialist vet at one of their offices and that’s when we learned there are better places to feel fatty deposits. I’ve had them try to teach me how to feel for body condition but weight is still the easier and more reliable indicator. We lost a Barred Rock suddenly the year before (we weren’t home then it happened) but I’m pretty sure it was the same issue. We used to give them occasional mealworms, but I’ve cut that out because of the fat content. The biggest issue is that we have a small urban yard, so the run area is about 130 square feet. We try to let them out a little but we have so many predators here, it’s really risky. Then, because if the heat, the heavier birds just don’t like to move around much in the summer months. I love her so much and I just want to find away to keep her safe without hurting the other girls.
