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.
