We have been losing a lot of chickens lately!! We had 7 'babies' who were about 6-8 weeks old, and lost 6 one day and one the next. Now in the last two days we have lost one full grown araucana, one 6-8 week old guinea and this morning one full grown black sex link and the baby she and another araucana were raising together. We initially suspected our dog, and we don't rule her out on ALL the killings, but she wasn't even outside for at least the last two. All we are able to find are feathers. Some of these happen during the day and others are happening at night...I am beside myself...what could it be???
