I can not keep throwing so much into the feed for my hens...they are not even laying right now, not sure why!!! I was told at the feed store that I could get a commercial grade concentrate and mix it with cracked corn and it would be half the cost...but...is that what is best? will that bring them back to laying again? I was getting 4-5 eggs a day at first...now I get a white egg every other day and occasionally a brown egg I have only had them (2 years old to a year old hens, 3 Americanas, and I don't know the other 3...a white one, a white and black one with feathers on her feet and a red one) for a month and have gone through 75# of start and grow. I also have 4 pullets that are 3 black copper maran and one blue andalusion, they should be laying any day now...so I was told to keep feeding what I was to the pullets and add oyster shell to the mix and then when the nights started to get cooler-I I read to help keep them warm at night to give them cracked corn just before they go to roost- no more than it would take them to eat in 15 minutes... There seems to be a lot of conflicting ideas as to what is best to feed them...I don't want them to be under nurished! I want them to start laying eggs again! Thank you!!!
