I have a 9.5 week salmon faverolle hen that eats and drinks normally but just doesn’t seem to be gaining weight. She has lots of feathers coming in but underneath it feels like skin and bones. She’s very active and often at the food bowl/happy to take treats. Not sure if it could be age related (ie. poultry growing pains) or something to be concerned over. The other chicks in the flock with her have a *lot* more heft to them but she’s my first faverolle so I’m wondering if it could be a breed thing? Whatever it is must not be contagious since no one else has this issue.
