Suddenly the brooder in my house is getting very smelly. I have cleaned it out entirely every other day with no problems and now the last couple of days it is out of control. It smells very bad and very strong, this is with only three chicks, also all of theri poop is runny not just every 5 or 6 times. Is this the sign of an illness? I will post recent pics of them in a moment.......... thanks in advance *update here* So I moved the brooder out in to my large outside coop. My coop houses 5 Barred Rocks and 3 Cochins and it doesn't smell. I went inside to refill the food and water and when I came back out it reeked to high heaven. It is definitely those three chicks. Is it possible that a breed of chicken can have stronger smelling poop than others? I don't get it. I had 6 barred rocks in that same brooder for 3.5 weeks with no smell. Now 3 Ameraucanas and it's smells like really strong human diarrhea or something-bad. I just keep thinking that there is something wrong with them! I clean out their enclosure 4 times in the last 11 days and it just won't stop stinking!!
