I'm looking for some advice as I try to gradually assimilate my new ducklings into their outside pen with my older flock. So far, it's not going great. The big ones are terrified of the little ones. I have been putting them together in the yard in the tractor with a fence between the two groups now for a few weeks. That part goes fine. Occasionally I just let them out in the yard together, and if the big ducks come anywhere nearby to get a drink or something, the little ones will chase them away. I assume this is similar to puppies with grown dogs and will eventually dissipate. I do need to think about moving them out of my kitchen though, and so I've tried a couple times to put them in a fenced in area in the duck run/coop. Problem is if they are on the side by the pond that has river rock, they will try to eat the pebbles - though I've never seen them swallow, usually pick them up and drop them, but I'm afraid to leave them unsupervised. If I put them on the wood shaving side they are eating the shavings like crazy, which is terrifying to me because I don't want any sort of blockage! Will they eventually stop eating them? I haven't been brave to leave them there longer than five minutes to see what will happen because I don't want a problem. But on the other hand, if I don't keep them there, everytime I try them on the shavings it will be novel and exciting and they'll probably eat them. Anyone with advice for how to handle this? Should I just wait a couple weeks and hope they're more mature and don't try to eat the shavings? They're almost fully feathered!
