Up until now, all the birds with this problem seem to be hens of laying age. I'd like to add an element & "stir the pot" so to speak, in hopes of figuring out the problem & the cure. I have Silkies & I have had 2 chicks now with a problem that seems very similar. I noticed the first one when it was just a week or so old, mainly because it was bald all around the vent & about an inch down the abdoman. When I examined it, the whole bald area was enlarged & very soft & squishy. The chick is about 2 months old now & the condition is still the same. I have it marked so I don't accidentally sell it to someone but apparently I did just that with a 2nd chick. One of my buyers came out to buy more chicks & she asked me to look at one of the ones she had bought last time she was out. It has the very same thing!! She said the chick was that way when she bought it but she thought it had just been picked on so didn't think anything about it until it started isolating itself from the other birds, at which time she brought it inside. It's now about 3 mos old & she's attached to it & wants to keep it & try curing it. Since she is so willing to try & help the chick, I gave her another chick anyway & now I'm on the hunt to try & find out what's going on with these two & to see what we can do to help them. Remember, this started when they were young chicks, don't know if they are hens or roos & the abdoman is swollen & squishy, like an underfilled waterbed. Any suggestions?
