I am super new to having chickens - l've had my girls for less than a week now. I have a nice mix of breeds (2 polish 2 silkies, partridge rock, buff brahma, mille fleur and a barred rock mix - they are all just under a year old). When I got them home I noticed at the very top of the black polish white crested hens head her feathers were short and just coming in – this morning I noticed she’s got a bald spot now and some dried up blood (not a lot) These chickens are just getting use to their new coop and living with each other. What should I do? Should I take her out? And if I do that once her head heal can I re-introduce her to the group – or will this just keep happening? And should I be putting anything on it? Cream?? Thank you in advance for any advice you can offer!!!!
