Help! We thought, due to the closeness in age (but for some reason, NOT size. they are HALF the size of our layers), the integration would be easy, but it's been HORRIBLE! First, we have one RIR and one Barred Rock. Both super sweet, always stay together etc. We bought a Buff and Australorp and brought them home. Kept them in a pen in the run the first day. That night put them in the coop while everyone was asleep. All was ok until they woke up and we heard SQUAWKING... we run out, and the two olders are chasing them all over the run. so i let the olders out to free range, and left the newbies in the run for 2 hours, to get used to the lay of the land. they had access to the coop as well, so they knew where home was. I then let them all out into the yard to free range, and stayed close to spray the olders when they would chase and peck. 10 hours later, they were able to come within 4 feet of eachother without chasing.. progress. That night, into the coop, but our RIR all of a sudden super aggressive in the coop! She was pecking at them to get them off their roost (a seperate one)... and even pecking at our hands in the coop! so i wanted until they all fell asleep. Same scenario the next day. so we put up a wire barrier in the run. i feel bad as now the olders are stuck on the side with no roosts, but i needed them with the coop to be able to lay their eggs.... so we do this daily, with no progress. The olders chase the littles the SECOND they all wake up, and will corner them in the coop if i dont get out there first. BIG BULLIES!!! then in the evening we let them all free range, but have to stay the whole time, or they'll get chased. This should NOT be this hard right??? The newbies are TINY. How long will i have to keep up this barrier??? any other suggestions???? we tried grass clipping pile to keep them distracted, but, they would not allow the newbies to eat or drink. they just chase them into the corner. so mean. It has been 5 days. Any advice would be great!
