I just got 2 chicks yesterday so today they are about 4-5 day old chickies. I wanted to get a silkie or a old english game chick but those arent available at the feed store until next week. Would it be ok to mix them in or would that not be good. And would 3 chickens be bad together? I heard somewhere if we only have 3 chickens 2 of them will gang up on the one. Any advice? Thank you!
