Hi I had 4 ex bat hens back in November, kept them apart from exisiting flock of 4 until 2 weeks ago, but Ive just noticed one of the ex bats is sneezing and generally still looking a bit scraggy (the other 3 now look lovely and are fully refeathered) - all are still pale combed but I suspect that will change as and when they start venturing out more (they are free to do so now, but only go into the coop now and again, not into the big wide world with the others - I'll push them a bit when the weather gets nicer). The sneezer is eating and drinking well and equally active as the others. Should I be worried and take action (like quarenteening her from the others) or do they get sniffles like us? Thanks F
