Hello everyone! I just bought a golden laced wyndotte and it is about a year old. The hen itself is friendly but it has a bald patch on its back, it also looks slightly irritated (reddish). The previous owner mentioned that it was bullied by a rooster constantly. I've had the hen for almost two weeks and I haven't seen any progress in feather growing. The hen has also been laying soft eggs every few days. I've been feeding it calcium through egg shells(crunched) and I plan to switch to oyster shells soon. Any ideas on what to do for both these situations?
