Hello! So I just received an email from Metzer Farms letting me know my 2 female ducklings will be shipping out Monday and arriving Wednesday! (So excited & nervous).. I have a bunch of last minute questions/double checking before they get here, if anyone can answer any I'd appreciate it! 1. For brewers yeast, can it just be any kind from the grocery store? Anything it cannot have/or should have in it? 2. I was told for the yeast, to use 1 tablespoon per cup, is this correct? My feeder holds 4 cups, so 4 tablespoons mixed in? 3. Can they have treats at any age as long as I provide chick grit? (lettuce, peas, etc..) 4. How long should they be on the 20% starter feed. Metzer says 3 weeks? 5. After the starter feed, is a 14% grower/finisher what they should be switched to? (This is what my adult drake eats) 6. I know that my adult drake should not mate with the ducklings until they are mature, but once they are big enough to be introduced, can they be together as long as I make sure he does not mate with them? (They only have access to their pool during free ranging time and can only do that when I am out there with them..) 7. Any tips on introducing? I have 2 adult ducks, one drake, one female. I was planning on waiting until the ducklings are bigger, so probably partially feathered (because I heard that drakes will try to kill babies). I will let them see each other as babies, but only with a fence in-between, I think it will be good for my adults to see them as they grow.. 8. What age can I let them swim in the bath tub for the first time? I've seen some people do it as early as a week? 9. Lastly, is it okay to handle the ducklings a lot? Like a few times a day? I see people letting theirs walk around the room or hold them on the couch, etc. Is it okay to do that even though they'll be away from their lamp during that time? And will handling them frequently help them be more tame as adults? Thank you!!
