Well I worked on introducing the new seramas to the coop. all of my birds are in the same coop because I only have one(But I remembered that we had a small little platform that we used for our Zip Line that is the perfect size for a some seramas, I have everything but hinges, and i will probably have to buy some more wire to make it a bit more predator proof) And I have two Black austrolorps and they are huge probably 5 lbs + and they Where TERRIFIED of the tinsey weincy seramas, They are Probably small size As, and my serama too that was in with them before is probably a large size C! I haven't weighed them yet so I am curious to see but it is funny seeing the big chickens cowering in the corner of the coop from the tiny seramas!
