A sweet person I know hatched a dozen chicks out for me. They were hatched the day before Father's Day and I drove a 4 hour round trip to pick them up. They were doing great. Then tragedy struck for the first time in our 10 years of raising chickens. My neighbor left and didn't realize his gate wasn't latched tight. When I came in the house about 4 pm on Sunday, the 10th to get a shower, she broke into my shed and killed 8 of the 12 chicks. I didn't hear the ruckus as I was in the shower. When I came out and saw the carnage, a foot here, a wing there, a dead body on the step and several in her yard, I was heart broken. She is a lab and has been acting more and more aggressive they past few months and no one knows why. She used to be such a sweet heart but lately has taken to attacking my dogs and other people's children. She tried to go after my husband when he went over to retrieve the bodies. My neighbor is mortified and keeps apologizing and trying to make it right. Four of the chicks escaped and hid under a vintage stove I have in the shed next to the brooder. They were scared out of there wits and it has taken about a week for them to calm down and return to normal. I had 4 BCMs, 6 white or blue EEers, one buff EEer and 1 blue Marans. The blue Marans escaped, as did one of the BCMs, the buff EEer and one of the white EEers. So I was pretty sure that of the 3 dead Marans, 2 were roosters and one was a hen. I think the two Marans left are hens. The EEers, I have no clue on. I am telling myself she killed the roosters so I don't feel so bad. Here is a picture of the 4 survivors. They are now 4 1/2 weeks old. Any guesses as to their gender? The two dead BCMs had combs twice the size of the two remaining ones and that was a week and a half ago. Any guesses on the EEers would be most helpful. I am not naming anyone until I am sure they are hens and are staying. Thanks. After finding out that the two blue Marans hens I bought back in May are really EEer roosters, then the massacre of July 10th, I don't think I can take any more bad chicken news.
