Questions on call ducks

[adorable]

I am so excited i am getting a pair with their 5 babies.They are 3 weeks old. I think. THis is my first time getting call ducks.
1st question is ...How long to i leave them on duck starter for?
2nd question....I know with rabbits you can mate mother with son. But with the call ducks can you do the same.?

I leave my call ducklings on non-medicated starter for 6-7 weeks. Then I start mixing 25% scratch to 75% starter for about 2 weeks. Then 50% starter to 50% scratch for 2 more weeks. Finally...I will get down to 50% scratch and 50% laying pellets or game bird feed.
(make sure you use a good quality scratch feed, one with only a small amount of corn)

Yes, you can breed mother to son with call ducks. I never do this but, you can.
Good luck with your new ducks , call ducks are a lot of fun.
