I hate that this has to be my first post here. I've been browsing here for some time and have found valuable advice on more than one occasion in these forums. On to the topic, I was closing my coop tonight when I noticed something wrong with one of my Ameraucana chicks. At first I thought a hen had plucked out all the feathers from her skull cap but, it was so much worse, her entire top part of her skull was missing, revealing the soft tissue underneath! This chick is kept in a side room inside the coop that is kept closed up (the chicks are hand raised and only about 7-8 weeks old) so I am at a loss as to how this injury occurred. Sometimes a grown hen or rooster will drop down into the chick's section from a rafter above, but I generally have to be the one to open the door and let them out and no adult chicken was trapped in there with them today. I also checked the coop for predators and haven't come up with any evidence of one yet, except for the injury of course. I love my chickens and want to give this little one a chance. She is in my house now, in a large dog crate. She's bright-eyed, alert and doing her 'where am I and where is everyone else?' chirping. After I brought her in I noticed she quickly began eating from her dish too. As for medical care, I've cleaned the top of her head carefully (this part made me so nervous, because her brain might be partially exposed) and put a large amount of antibiotic ointment on it. What I need to know is, what do you think could've caused this and, what else can I do to help her? We are not in a good financial situation at all atm so taking her to a vet is unfortunately not an option. Thank you so much for any help and advice!
