My girls are on a mixed flock - game bird/turkey feed from Blue Seal/Kent group. Have been for well over a year almost exclusively. (DH will sometimes stop at TSC and pick up feed). Have free access to oyster shells , free range and get gleanings from the garden. After an animal attack that cost me half my flock - I noticed my Naked Necks had a cold- my Cochin Roo was already isolated with a SPeckled Sussex hen(she passed within a couple of days of attack) so in they came for a round of Sulfa & domething else the Vet ordered. Ok Cochin fine after a round and he's back out with the rest- no other signs of respiratory issues. But my 2 NN hens were iso'd well over three weeks ago and were starting to show signs if egg binding. One was standing and walking like a penguin. Notice fluid build up in abdomen and tried another round of antibiotics. In the mean time one of my Leghorns was showing posturing of egg binding. Squatting and ruffled- she came in about a week ago and was started on antibiotics for fluid build up in tummy. She was oozing clear liquid and no signs of an egg. I took the one NN who was penguin walking to the Vet who for $200 told me it was a tumor and not egg binding... But I was massaging the external portion if their vents and FELT hard objects what seemed like eggs tips. She just in massaging and greasing up backsides the two passed rubbery multi layered masses (much like I found in a hen who was egg bound earlier in the year after she passed) no one has passed an egg - all three hens had been given a round of antibiotics and probiotics with calcium supplement. What am I doing to my hens- this makes 5, which I tthink is quite high for a small flock of 25 birds from McMurray. All hens lost to egg binding have been from my original order from McMurray that I got in May 2010. Not sure if it is a breed thing with Leghorns and RIR but then my Naked necks are afflicted. Any help? I only have 6 hens left.
