My girls are Black Sex Link and they are 24 weeks old tomorrow. They are housed in a hen house with access to a spacious outside run. We use pine shavings as the litter in the house and change it regularly. They are fed a layer ration with grit and shell given as free choice. I change their water at least twice a day to make sure they have plenty of fresh water. The girls started laying at the beginning of August and we are almost to the point where everyone (all 24) is laying. On Saturday morning as I went out to open the door to the run I found one of my girls dead under the roost. No sign of a reason. Everyone seemed very healthy and happy. Sunday evening I found another hen in the corner of the run by herself. When I checked on her she was very pale and inactive. We pulled her out and checked her over. She has diarrhea but no discharge from her eyes or nose. She was panting but felt cool. We put her in a small cage with a heat lamp and started giving her some sugar water through a dropper. About 11:30 last night she started drinking on her own but still is not eating. This morning she is still alive but still very pale and inactive. I would assume this is Cocci but thought it odd that they have been healthy for 6 months and now get sick. This is the first time we have lost a girl. What is the best way to handle this illness so as to not lose anymore girls? How does this affect the eggs, can we still use them or should we stop using the eggs until it is all cleared? I am so sad for my babies and want to make sure I do the right thing for them. Any help you can offer would be greatly appreciated.
