My neighbor has a store so he produces a lot of eggs, and butchers for meat. Right now hes got 165 layers, 100 meat chicks, and it getting 400 more meat chicks by summer... And hes got 100 more layers comming! hes crazy. In his coop with the layers it isnt healthy in there. The smell in the layer coop is SO Strong, smells so sour and I bet you would get high off the smell. Hes got 4 roosters in the coop, one rooster is in bad shape, his foot is completely swellen and his spur is completly gone! and he was bleeding a lot, the few of the hens were pecking him. 99.9% of the hens are tore up, they have there back feathers missing ( I dont believe there getting over mated... 4 roos to 161 hens!) There are a few hens which barley 10 feathers on them,pretty much complety balled. There is about 2 inches of poop on the ground, nothing but poop. they have a run. With is a ok size. the coop is pretty crowded. when me and my cousin went in his coop, there was 2 dead hens on the ground whom died on being egg bound. Its really bad, but theres nothing I can do... Hes really nice man, he gives me hatching eggs for $3.00. Really busy too. but idk I want to do something but there is nothing I can do.
