They are fast! mine do that too, as soon as the see my coming to the run, they FLY off the outdoor roost, some crashing into the run gate hahaha poor goofballs! They are hoping I am bringing them kale from the garden,,,,,,,Yes. The silkies will be happy today. They yell at me to let them out as soon as they hear me. I had to catch an escapee yesterday because she ran under my foot as I was coming in her pen. The 2 month old half silkie chicks can sort of fly and I had 3 of them bounce off me because their moms have taught them to make a dash for the door.
