I have 2, 6 week old EE pullets that right now are living in the grow-out pen. They have a ton of room in there, but I have a broody that is due to hatch in the next 2-3 weeks and that is the only place we can put her. Will the babies be old enough at 9-10 weeks to go into the big flock? They have never met each other, but I am working on trying to build a little playpen I can add into the big run. Another problem I have is the ducks. They live in the with chickens and have their own kiddie pool. The adults are big enough that the water only comes up to their knees, but I'm afraid that the pullets will get in there and drown. There are bricks in there that they could get onto if they fall in.
