My little ones are 5 weeks old and have been in my house that long. The weather this week is good. 70's during day and 50/60 at night. Well my house was smelling like a chicken coop. My sweet hubby had just built himself a new building so my guy decided to build brooder inside his shed to get them out of the house. YEAH! They are all doing great together. I mean smell in the house was bad , 25 bird are stinky..glad that is over. Lol. Today was a big cleaning day for sure.
