My layers will jump actually jump the meaty fence to attack them, i have to watch them close... My wyandottes are pretty aggressive to new birds. My EE and BPR just ignore them tho. The guineas are also very aggressive towards the meaties. they do all free range but are pretty far away from one another. Red, my wyandotte roo, will follow me all over the property at feeding time and he just ignores them all. (he knows momma is a sucker for his handsome cluck noises
and he gets a few extra treats from the pig slop bucket) Am frustrated that my best layers seem to not like new additions. They are gong to hate me come spring, plans are for some marans and orpingtons next year. I am not doing another set of meaties till spring. The weather is just to iffy, and would have to invest in more heated waterers. Looked at a few options at the stores over the weekend.
