I have been loosing chicks all Summer to bacterial infection. I have been treating them with ant-bacterials in their water but I hardly have any left. I am so mad, such beautiful weather and we sure needed all the moisture but I wish i had more chicks to show for all my broody hen's work. My Bantam Buff Cochin pair and Esmeranda, the Show Girl, have only lost 1 of their 7. They know something I don't.
I understand your frustration- my stage one grower pen had a leaky roof just as spring ended, and I just kept thinking, "well the dry summer is just around the corner." Instead the pen got soaked repeatedly with each rain and I have been fighting losing chicks to Cocci all summer long even with frequent bedding changes and medication. Finally got the roof fixed two or three weeks ago just as the rains stopped, of course! Hope that means my losses are over.
