My two bantam Silkies roost right along with the rest of the bantam flock (EEs and Welsummers) because, I believe, they were all raised together and since tiny chicks they all had small ramps, pint size roosts and other home built "jungle gym" toys to play with. As they grew the size of their toys grew along with them and now all of them troop up and down the ramps to the nest boxes and up to their second floor roost. The silkies get absolutely no lift at all when they flap their wings but BOY CAN THEY JUMP UP!! But please don't ask them to jump down off a roost because they drop like a sack of potatoes!
I was led to believe the Silkies would be the bottom of the pecking order but mine are always bossing around the Welsummers. When I move items around in their large yard, which I do almost weekly, the Silkies are usually the first to come and inspect what the new chair, toy, dish, food, waterer, etc. is. I keep an old metal chair in the yard to read the days mail with them and if I'm eating a muffin it will be either the head EE or a Silkie that jumps into my lap to share the news (and the muffin). When an occasional puddle happens in their yard the silkies are the first to walk into it and start scratching and pecking. Fearless or too dumb to be afraid or somewhere in between? I don't care and they don't either.
Yes my Silkies have gone broody, but then so did two of my four EEs and for a longer time than the Silkies. My 8 gals average 5.5 eggs a day and, lucky me, my Silkies lay soft pink eggs. I'm happy my gals roost together so they aren't sleeping in their poo. I would certainly have Silkies again, LOVE 'EM!
