birds in a joining Flight

Can I fly Silvered eared Mesia and Pekin Robins in adjoining flights
My Siliver eared built 2 nest layed 2 eggs each time and deserted them.
I have other birds in with them in 8mtr. by 5mtr. with plenty of srubs and small trees.
The flight beside them I've Snowy crowned robin chats 5mtr x2mte. could I put my pekin Robins
in with them.

I know it's difficult if you have a large aviary not wanting to put more than one kind in there and lots of people get away with it but it may be the reason that they deserted. I would have thought that Pekins and Silver eared next to each other would be OK as long as they couldn't interfere. I have two pair of Silver eared Mesia and they are in separate aviaries but can see and hear each other and it doesn't appear to cause problems with breeding.

I've seen one of your articles before about your silver eared Mesia and I separated my pairs with a complete flight between them. I was hoping to put the Pekin Robins in the flight between them. at present my Pekin Robins are indoor. and I'm not happy with them there.
thanks for your help and advice any other information will be appreciated

Our Silver eared Mesia are in opposite aviaries so I guess there is about two feet between them. I think that probably works as they can't actually land on the same piece of wire netting so I suppose there is no threat. Not sure if it would work well if they could make contact. By the way our pair of Pekins have never bred they have made nests and the hen has sat on the nest but no eggs.
