I have just added 5 new 10 wk old Brown Shaver Pullets to my existing flock of 5 mixed breeds. I read some posts before doing it and added them last night while the girls were all sleeping. It seems fine this morning until I fed them and the 2 girls that aren't broody at the moment kept chasing the baby's away, I have fed them separately but I'm concerned that everything will go pear shaped and the new chicks will get a really hard time from my other girls who are approx 12 mths old. Any idea's on how to keep harmony in the house? ..................chicken house that is!
