Cochin Pullet acting sluggish and slow and sleepy and she has an empty crop. The coop has been cleaned out of all the hay that was laying on top of the mud and trapping amonia ..... Bantam Rooster has recooperated but suffered from amonia and lack of fresh air... while cleaning out the coop I ran across a layer of mold in the corner near the water container. If my Molly (30 week old blue cochin pullet) has mold in her crop, how should I treat her? And how do I rid the mold from the chicken yard? Any suggestions or pointers?
