Hi all! New to the forum and to the chicken world. We reside in Pa. We started our flock in April. We purchased 7 ( 5 RIRs and 2 leghorns) hens. Three weeks later we purchased 6 Americaunas ( which turned out to be a mix bunch. One suspected to be a BR hen and a docile, entertaining, watchdog roo). In June we picked up 8-18wk old RIRs. We've been fortunate with them sorting out their differences and it seemed the flocks stuck together with the Americauna mixes getting the brunt of the bullying. Nothing more than being chased a few inches. This past Saturday we opened the coop to find the black Americauna had fell to her death and broke her neck. She was the underdog and always picked on. We accepted to be that and have slowly move on. Only to go out this morning and find one of the older RIR hens that we purchased in June, DEAD. A few feathers missing but no blood. I haven't noticed any pecking issues as discussed in many forums and magazines. I'm stunned and so disheartened. They have 120 sft coop, a sizable area that is still under construction....I just can't put a handle on knowing what is going on! The coop (reformed shed) doors are open from 5 am until dark. We aren't sure if the first death happened after the coop was opened for the day or through the night. Hubby has paid special attention each morning and counts them now. They were all alive and counted for today. Our son believes the "Americauna" aka barred rock hen is the aggressor but up to the time of the black hens death was picked on. Any insight, tips, etc to avoid this? Our last set of hens just peaked 18 wks and will be laying any day. They are all the same size. Thanks and I apologize for the lengthy post. Needed to give all info possible.
