Not a trace, there was no snow so tracks would not be present. But feathers should have been somewhere in the yard. And given that the roo was at least 8 pounds if not almost 9 pounds, I just don't see the hawk flying away with him.
I typically sell to people who are not the least bit interested in visiting my chicken yard. I don't ask why they want chickens but are not prepared to step in a bit of chicken poo. I just take it that they are getting started and will gradually adjust to the larger blobs of a laying hen or worse a broody.
Many times I do get asked if I think they need heat in the coop and the coop is one of the made for 3 from RK or amazon. I tell them no heat once the chicks are outside but not to put them outside until they are fully feathered even on their bellies. There just is no room for a heat lamp and a cooler area in those coops.
I may need to start meeting with people away from my property, but they can still find my house pretty easily our coops are visible from the road. I have thought of giant locks but those are easily broken. For the most part the loss of a hen is only valued at $25 or less but with a breeder roo or hen it is so much more as I'm trying to expand my flock and sell the mixed chicks for feed money. Without that roo in the layer pen, the mixed flock fertility will go down for another 2-3 months. So while I have backup breeders for the HRIR, my layer flock roosters are still quite young and I was using the spare RIR roos to get fertile eggs from the layer flock.
Some one else on the heritage large fowl thread said they would not sell their best breeder for $200 but they also said they would not pay $200 for a breeder as well. It kind of puts things in perspective, sure I would not pay a fortune for a rooster but I do highly value my breeder chickens.
The father of one of my roosters just sold for 600.00 I just about fell over when I found that out. He is staying in the breeder pen for sure!
If your roo was very nice there is always the possibility some one took him. Seems like they would have taken more than just one bird though.
