Hello all. I have had two chicks in the same run as my four nine month olds - separated by a secure gate, since they were five weeks olds and have let them out with the big girls for a few "get to know you visits" they were chased but no serious pecking going on. Well today I tock down the separator, the little girls now twelve wks old, got chased and hid in the nest/egg box, but got pushed out when one of the big girls wanted to lay. How do I keep the little girls out of the egg box (I only have one but will add another when the two little ones are close to laying age)? At the moment the little ones are in the coop (with there food and water, I got Manna Pro Triple Duty feed for them all and have calcium out for the laying girls) and the big girls are in the run (both connected by a big open door) also with food and water. Will it take long for them to become 'friends'? Im a very nervous chicken mom! Thanks for you input.
