I had 4 rir and 2 welsummers. Now I have l welsummers, a hawk got one welsummers, darn it. And l rir a crippled one, when I added 2 ze bras to them, so I was getting down , I added it slowly, they are bthe same age. I watched after I added it and they were fine, no fighting. I checked 2 other times and no fighting, I checked at night, and the crippled rir was dead, kind warm, so I think it was soon. Looked fine, but eyes looked funny., maybe pecked? So what do you think happened. I am, now afraid to add to my flock?
