Myrtle fractured her leg. I discovered that some bone was poking through, so I cleaned it, feed her water by dropped with aspirin and kept her in her coop for three days. We then kept her in her coop for most the morning, but opened the door mid-day and she would hope out on one leg.
It took about two weeks before she would put pressure on it, but she only has a slight limp now. She has a bump that has totally healed on her leg, but she is doing great.
Egg production has slowed. Both chickens are laying all over the place; under tables, under the oak tree, behind my treadmill. The have made a nest out the the plastic bag that holds the pine shavings for their coop and are laying there. I know Hazel is doing that, but I haven't witnessed Myrtle laying at all. I actually wondered if she is laying period. She must be, although our eggs have been markedly Hazelesque recently; browner with speckles.
I referenced the Backyard Chickens forum for help when she was injured and I got great advice. She nice and knowledgeable people who said to just trust your instinct on how to treat her. It was good to hear that because I couldn't do much else. I made sure she got plenty of water, aspirin for pain and cleaned her injury.
We are pretty sure that she fell or something fell on her, becuase if a racoon got her, he would have eaten her.
