I have a small chicken tractor type coop in my bedroom for my 2 month old bantam frizzle hen. It's really way too big for her. I'm going to be getting 2 mallard ducklings and 4 chicks on Wednesday. I want to keep them with my hen in the big coop that way they can grow up in there and I won't have to keep moving them. I usually keep my chicks in a 20g fish tank but it's smashed. If I provide a heat lamp and keep my room warm will the 6 of them be okay in a big area like that? I'm pretty sure Pidgey the frizzle will not bother them and might even make friends but in general do young hens get along with babies?
