I have three hens, one Americana and two easter egg chickens that are 16 months old. Recently my Americana chicken stopped laying. I thought brooding until more than 8 weeks past and still no eggs. I was planning on taking her to the vet but recently I found that all the chickens have stopped laying! I think it may be stress and the fact that something may be trying to get at them! Apparently my mom found some feathers on the ground and saw that one of americanas tail had been pulled out! I'm I don't know what I should do and ive never been more scared! Please someone tell me what I might be happening and what I can do to protect them. We have hawks in the area but their enclosure is carefully covered so it must be something like a possum! Please help!
