I have 5 Indian Runner ducks. Their are 2 girls and 3 boys. One of my girls seems to want to go off by herself for some reason. I notice her beak isn't as yellow as the rest of the ducks. They are all happy together but this one little girl just seems to sit back to see of the others notice if she is there. Kind of odd. She doesn't seem sick. I find her by herself a lot though. Any ideas?? BTW, they were born in April so they are 7 months old. Out of the two girls I think only 1 lays an egg. I get an egg everyday but never had 2 eggs. I feed them flock raiser and they get some scratch and some BOSS. I do let them free range most days.
