We strengthened the pen using 2 x 4's to keep the welded wire between the wood instead of outside or just inside , we even put up wood across spacing them 3 inches apart long ways so that nothing could get in.........large dog got into my pen again ripping the wood apart using its teeth. We caught the dog didnt tell the owner I am sick of dealing with owners and we did away with the dog our self. But how many more dogs can this man have of course 5 more waiting to break off their chains and go crazy. They don't give their pets attention, they are out in all kinds of weather and 107 degree heat. I feel like giving up owning chickens my chickens wont even free range any more during the day they are too afraid to come out of the coop and egg production is 0 now. The only chickens that are safe are the ones I keep in my house my bantams and 5 baby chicks. I only started in April 2010 since then have lost total of 13 chickens. Whats the use of having a 6 ft fence if a dog can bull its way right through it , we have 6ft welded horse fence it was bran new when we first moved here a yr ago. When I say right through it I don't mean under it I mean through it busted a big hole right through it. If I had a flock of 100 or even 50 a few chicken losses wouldn't be so hard I guess I don't know if I would feel the same. But I only had around 27 chickens each we named I will never name a chicken again. It is so emotional to be so attached to them. I don't like putting other peoples pets down I feel it isn't fair to the dog cause they have sucky owners. My question is does it get better or does it get worse.....dealing with predators and loss? I guess the only way to keep chickens completely safe is by using METAL cages where their feet never touch the earth..that just doesn't seem fair either to me since its natural for chickens to scratch for their food. But when they are suppose to be safe in their Pen away from predators but the predator is capable or ripping wood to shreds it seems I will never win. It is a problem when I can't afford such cages I am not rich or well off I hate admitting that but it is the truth and I have been doing the best I could with what I had. You would think being in the country my worst predator would be wild life.....not domestic pets... Sorry Just venting I know the only solution is giving up on my love for chickens or put them all in wire cages off the ground.
