i don’t know whether or not I should be concerned. My hen , along with two other of the same age started laying at about four and a half months old. We had a hot spell and my barred rock appeared to really be suffering from the heat. Her comb flopped over and she stopped laying. It has cooled off but she’s still not laying. It’s been at least a month since she laid. Her comb is looking better, still red, she’s still squatting for me, but no eggs. Should I be concerned?
Juvenile moltings are done by about 6 months.
The first adult molt usually happens around 18 months,
give or take a few months depending on geographical location,
but younger birds can have a partial molt before then.
I had a pullet have a partial molt at 9 months, and have read of many others.
Do you free range?
Vet did a fecal float?
Have you checked for external parasites?
