I haven't been on here much, as my goats are keeping me on my toes (breeding, roundworm issues, etc....). My pullets, hatched in March, haven't been laying since August. Some look to be missing a few feathers on their heads near their combs, and a few throughout their body. This is a variety of breeds, to include EEs, BOs, BAs, and RSLs. The RSLs hung on the longest, and are the only ones I actually KNOW for sure were ever laying. The last one to stop laying stopped 2-3 weeks ago. My seven month old EE Roo is still not crowing or pursuing pullets. I also am having trouble with my younger batch of chicks, hatched in mid June. No signs of laying, and I have had several up and die. Not all at once, but here and there. A few just went missing here and there, but others I have found in the chicken coop dead. Most seemed perky and alright until I found them dead. One was perky until the night before she died. I found her standing near where my adult goat sleeps, sort of lethargic, and thought maybe she got stepped on. The day before, she had been hopping up on my doe's back to check out what food I had. No off stools that I have seen. There are two young Roos (leghorns) whose combs seem droopy and they seem a bit off. Their other leghorn Roo buddy got a droopy wing and comb before he died 3-4 weeks ago. He wasn't gimpy, just huddled a lot and looked off. It's not been a glut of losses, just one at a time, here and there. Not one particular breed either. A couple of losses we know are due to a predator (nearly full grown turkey's head was taken off nearly eight weeks ago, a hawk got a Polish). So far, our full size older chickens (7-8 months old) don't seem to be affected, unless the lack of eggs is any indicator. Any thoughts on what might be going on?
