I have 4 feed store type birds right now. Welsummer, EE, Production RIR, and Black Sex Link. I want to add some prettier birds to my flock. I have the space for a few more. I have some breeds picked out and would like opinions on which are most likely to cause trouble by flying over walls. We have a 5-6ft block wall that surrounds our backyard. The chickens I have now stay on the grass side of the yard which has 20ft tall bushes along the wall but there are sections that don't have the bushes that flighty birds could get over if they wanted to fly up 5-6ft. Production is not an issue. It's only my bf and I here and having 4 production birds already we should be fine with egg numbers. We have people to give extras to but I mainly just want birds that are pretty and fun to watch.
Here's my list. All opinions are welcome to which breeds I may have issues with.
Large foul-
Cochin
Wyandotte
Brahma
Marans
Faverolle
Sultan
Orphington
Polish- have read mixed things about their flightiness
Speckled Sussex- have read that they can be escape artists which would be bad.
Bantams-
silkie
cochin
I've already removed d'Uccle and leghorns from my list because I read that they are flighty
Thanks for any help you can give.

I had two silver laced wyndottes and they were beautiful girls, more on the quiet side. I also just got some silkies and they are so cute and docile! Silkies can't fly so you won't have to worry about them getting out. I do have three white leghorns as well - we trimmed their wings a few times and they don't try to fly anymore. But I do know they can be flighty. But they have great personality. Good Luck with your decision!! HAHA. I want them all
