I have 5 pullets that were hatched the end of April. One had started laying in october then I think another one started laying middle of november. Then it got really really cold. Like average of 16 during the day single digits during the night and the eggs stopped. They have a nice coop with good ventalation no drafts lots of pine shavings and straw. There are 3 red sex links two of these are the ones that had started laying and stopped. And 2 americunas. Havnt seen an egg from them yet. but i know they are usually later than other breeds. Is it normal for them to delay laying due to the cold? They get 22% feed plus oyster shell which they eat like crazy. Tons of treats from the kitchen. Soaked alfalfa pellets a couple times a week. Oatmeal and I change out their water multiple times a day with luke warm water as it freezes pretty fast. I do not provide supplemental light or heat. Could it be because of the short days? I thought that a young pullet would lay regardless of the day length though I could be wrong. Any and all help greatly appreciated.
