Thank you for viewing my post...a local friend of mine acquired a flock of 10 chickens today. They were hatched in mid July the seller says, which would put that at about 5 months old, but are the size of 2 month old chickens. They are NOT bantams they are LF Orpingtons. I raise LF Orpingtons and mine at 5 months of age are usually around 8 lbs. hers are 2-3 lbs. They are extremely skinny, their breast bone as no meat on it and you can even feel their hip bones, their skin stays in place when you pull it up which I think would mean they are dehydrated. She has started them on probiotics in the water and is giving them flock raiser as their main feed then a treat that is equally mixed with Whole Corn, Rolled Oats, Calf-Manna and BOSS. My question is will they get to full size eventually or will they always be on the smaller side due to being starved of food and water? What can we do to get mass on them quickly? Thanks so much for any help you can give us!
