I have a 1 year old B.O. who for the past several days hasn't been right. I did warm bath x2 and tonight helped pull a broken cracked egg from her vent. Her comb is still red, I fed her olive oil soaked bread and she ate quite well is drinking but just more lethargic. Do I need to do anything else for her. I have her inside for the night with me. Should I start an antibiotic and which one how much? Sorry a newbie to this and she's one of my babies. Thanks
