I let the chickens roam the garden for few hours a day, then one day i notice a poop below their roosting pole, looked all red and very messy, poop mixed with blood???? they could have eaten rasberries too???/ I have 4 birds and only one is laying, there were 2 laying and then the bloody poop now only one egg. Is it that they stopped laying already, is it time for a light? did something awful happen to one of my chickens? I'm so new at this so I'm worried, they are all so happy and healthy and no more nasty poops... help?
