Wow. There's one thing I've learned from participating in these forums is that bad things happen to good chicken owners. This is the first time we have had hens and the learning curve is steep and unfortunately results in some losses which we have found to be devastating as these are our pets.
I take offense to your tone that maybe I shouldn't have the two birds I have. As for our first loss was from one of my children mishandling the bird and she was unable to recover from the injury. We talked to our kids more about proper handling. As for the other loss, which just happened this weekend so maybe pardon my sensitivity, was as a result of our friends dog being let out by my daughter. These things HAPPEN, especially with children in the house.
I don't fault my kids, they're kids. That's why it's called an accident. Yes, we learned from them but do I think for a minute that means we shouldn't have our birds? No. For heaven's sake, we live in the city and we almost had a hawk attack in the summer. How would I have been able to prevent that? I see people on here all the time with talk of dog attacks/injuries and the like, it happens.
As for your other question, no I really don't want to add any more birds right now. We have a small coop that was only ever intended to house the four of them and I think we may have underestimated their size, so it is on the small side. Another learning process. My question was about their welfare, about whether I SHOULD add more birds. If I don't need to...then I don't want to.
