I was given 2 grown hens and a grown rooster, which i am pretty sure they are just now laying age. I also was given 2 baby chicks which were i am guessing were less then a week old. i have become very attached to the little ones. i feel its getting time to slowly add them with the others. i am pretty sure one is a hen and the other a rooster. will the big one get along with the little one or should i keep them separated from the start? This is my first time having chickens of my own.
