Hi, I have a sick bird. My beautiful blue orp. She's has clear liquid milky poo, lethargic, pale comb and waddles, hasn't laid an egg in 2 months. I've lost a few birds from this coop, most recently my beautiful son of Suede roo. Need some help. I have her isolated, in a pen gave her some Vet RX last night, has Antibiotic in her water, but I'm not supposed to give them to hens over 16 weeks and she is, but I didn't know what else to give her. Please help, I can't loose more girls.
