Yesterday one of my hens was attacked by a roo and lost a lot of feathers, had a big cut in her head and bleed a bit. A good chunk of the day was spent cleaning and tending to wounds and making an area for her to rest separate from the other chicks. She has a sister that paced nervously outside her pen for hours on end so I let her in with the hurt hen and they've been keeping each other company. The healthy hen has no desire to hurt the other chick, she just sits near her and coos when I walk up. It was a rough day for chicks yesterday but today has been a bit easier and my little hen is dealing with me needing to clean her wounds and treat her. The sad part was that I have never heard a real pained cry from a chick before and it is heartbreaking.
Hope he heals up. Hate seeing an injured chicken. it's hard to believe the things they'll do to each other.
