I have a 3 week old chick tiat I noticed had a bloody tail stump. It is one of the bigger chicks but the others are pecking at her/him. what can I do to stop this? I ahve removed her from the others. How do I fix her butt(it's not her vent.) Do I need to get some more protein in the chicks? how do I heal the bloody chick? do I wash her? I don't have a larger space for them, there are now 8 in a 50 gal rubbermaid tub. What do i do?
