my chickens are rescue battery hens and are still growint their feathers. chloe was totally bald and it is taking a little more time for her. we recently introduced a new bird into the flock and there were no signs of anything wrong. this morning i found chloe hiding in a corner while the new bird pecked at her vent. she was bleeding badly and her vent is very swollen. i isolated the new bird and took chloe inside and gave her a warm bath and cleaned her vent. there is quite a lot of damage. i applied sudocream to the areas that werent too bad and she is now in my bedroom shes sore but was able to poo although it was quite watery and she ate some mashed vegetables. Should i take her to the vet to get antibiotics or should i apply topical antibiotic cream?
