I made a difficult decision tonight, after repeated Hawk attacks and a 50% loss on the last broody chicks DH and I went out and took the last four chicks from the hens.. All are 3+ weeks old but I just cannot allow the hawk to keep harassing these little ones all day, Hens kept them all close to or in the coop for the last two days because this crazy bird is so committed. My chickens free range 1/3 acre so there is no way to cover it, we have cedar trees and lots of cover but it didn't matter... Next year we will be ready, once our Oregon rains taper off this winter were adding on a broody coop and a separate run (completely enclosed) for the hens to raise the chicks, when the hens decide they are done raising them. hens go, chicks stay until they are not as tempting. I know the hawk is doing what hawks do but it was sad to hear the mommas clucking for the babies... Got a hen due to hatch her chicks hopefully by this weekend, I'll let her have them for a few days to make sure they are eating and drinking then sadly, I'll be taking them too. I didn't get into backyard chickens to feed the local wildlife.
