but im not sure what, or even if there is anything wrong.
she had stopped laying and she had a very dirty bottom and was having diarrhoea so wormed all the chooks.
she is eating, drinking, laying again, pecking and scratching around and her comb is red but she still looks thin and has a thinner crop then the other two hens, she has a kind of ridge of feathers down her breast.
could that just be a side effect of worms and it will take a while to fatten her up again? or do i need to take her to the vet?
