We have 5 chicks, 4 americauna and a rhode island. One of the americaunas, Ruby (who belongs to my 8 year old) continually pecks at the rhode island, CC (who belongs to my 11 year old). We have tried trimming a bit off of her beak, which caused concerns of it's own, but she is still picking away at CC's wings. What can we do? The chicks are in a box that is quite adequate space wise. They have a feeder that has 7 spaces, a big waterer, and pine shavings on the floor. Ruby never picks at the youngest chick, who we got as a replacement for one who died, but she seems facinated with CC's feathers. What can we do?
