Hi, I am new to keeping chickens, got 3 girls 2 weeks ago. A light sussex, a bluebell and what i thought was a rhode island red. The rhode island had a bit of a runny nose when i got her home but i put it down to the journey, change of scene etc. Yesterday she had a nose bleed and had been sneezing for a few days. I phoned the nursery where i bought her and it turns out she was some type of rhode island bantam?? They said they would take her back as that wasnt what i wanted (i just thought she was young and thats why she was small?) I did say i was a novice :-/ When i got there i was told she was a befordshire something?? Anyway, i chose a silver sussex. When i got her home i put her with the other 2 and they have been chasing her and they have all been growling. Will this settle down? And to top this off, the light sussex looked like she had a snotty nose! Terrified that the bantam had a cold and now the others might have it.
