I am new to keeping silkie hen as a pet and have just notice one of my hens keeps parting her feathers on her back and what looks like biting.
After a quick inspection I noticed that she seems to have some kind of growth, the growth comes straight up from the skin, not anormal in colour is about 1/2cm in height and 2-3mm in width and circular.
Does anyone know what this may be???
Thanks for your help
