hello, i have a 4 week old silkie pullet and a 4 week old cockerel black japanese. today i just got 2 4 day old chicks one Rhode island red and the other is an americana. i have them in the same coop rite now which is not very big maybe 3'x3'x3' ,the chickens will eventually be free range chickens . as for now will the chickens be alright together? it is bed time for them and everytime i go out and look the silkie is sitting on them while they sleep, but when they get up and move around and the 4 day old chicks eat the older ones will steal the food from them but dont look too agressive yet.
