X2Just a thought - but maybe try wood rather than metal perch? Maybe a 3" rounded top wood perch? I have a 2" rounded top wood perch and even my LF like it.
There's no way they are going to be comfortable on that if they are slipping. I use rounded edge 2x2s
I sold most of them! I still have 4 Ameraucanas and 1 BCM that sleep in the nest! Every night I put them on the roost! Picture of the thing! If I where a three week old chick I would like a gym to climb on! The first tier is about 12" off the ground!
