#5 is happy and eats anything that happens to move towards his mouth. #4 is a bit stroppy and has to be force-fed. He won't willingly take anything I offer. #3, who I thought would teach the others, has become confused, and sometimes takes the food i give him, and sometimes begs from the others.
#5 is much smaller than his sibling and only half the size of #3. I hope he makes it and doesn't get the "soft bone" syndrome that killed my first bird. Boosting the calcium doesn't work - peewees get kidney stones.
