We have 4 chicks that due to space issues we have to put together. Two are 6 weeks old and two are 2 weeks old. Oddly enough three of them are identical in size and only one is a "big girl" (at least double the size). It's been 85+ degree weather so we've been putting them all out in the yard for their daily worm and bug buffet together and they seem to all get along ok except for the big girl occasionally nipping at the babies when they get too close. This afternoon we put them all in our chick-n-hutch and Coco the 6 week old became a real bully not letting the babies near the food and trying to eat it all herself. They kept huddling in a corner so I made a little getaway box for them by standing a cardboard box with the open top towards the outside wall of the hutch and cut a small door in the side that the little ones could run through without Coco following. Should I separate the big one out for a while or just let them learn to get along? What should I do about food for the little ones? They can sometimes get to it but then get chased away after a minute or two. Thanks for your insight and this wonderful website!
