HI my sister has got three chickens she has had them for 2 weeks now and theey are doing yellow poo, she has all the books ect ect and has collected a sample and is now waiting on the place she brought them from,

The toilet from what i understand keeps going to normal then to this yellow stuff, They have the run of the garden and I must say they are very happy,, They do make some funny noises, i had no idea chickens where so vocal

Please help do you have any idea what this could be, so i can pass it onto my sister,(she is takeing them to the vet by the way, but sometime owners are the best source of advice)

Em
