I've tried to keep a chick with scissor beak. She lasted about 4-5 months, then died. When she was born, all looked fine. About a week old, we noticed s slight shift in her beak. She was eating and drinking fine. The beak got worse almost over night and progressive got really bad. In her last days we had made provisions for her. Put her food and water at elevated levels. If she ate/drank at ground level, it would just fall out. Had to clean her beak several times daily. The food would get stuck & become pasty stuck on her beak. The other chicks would sometimes help with that process and peck at her beak. In the end, she spent so much time eating and drinking. The other chicks would be sleeping, not her. She was smaller than the others too.
I wish you luck with your chick. Ive only had one born with it since the other one died. I culled it immediately. But it's your decision. Please keep us posted.
