Backstory- We got 5 chickens online, 2 RIR, a buff, barred rock and Silver laced wyandotte online as chicks, they were raised together. About a month ago, we got rid of the Buff orpington because it turned out SHE was a HE, even though we ordered pullets only. To replace him, we got a third RIR that was about 2-3 weeks older than our current flock, thinking the transition might be a little bit easier. theyre 16 weeks now, and the newer, older RIR is 20-22 weeks old. She has transitioned well, although the others do pick on her a bit... not violent, but chasing after her when I am giving out treats and such. Any advice on how to reduce this? The other issue im having is that the new pullet sleeps in the nesting box! shes close to laying age so I dont want to block it off (it was blocked off until about 2 weeks ago). We got ceramic eggs to put in there but she just lays on top of them and goes to sleep. I need some advice! please help!
