Thank you all so much for my welcomes.
2 more chicks died unfortunately.
I found out today that the food i have been giving them was only 18% protein, so i have managed to purchase today a 22% protein chick feed, supplier said he can get me a 24% medicated starter chick food tomorrow, i so hope this will be the end of my problems. I have also today built a new pen for the poults with no corners. Also have decided not to put them on straw, so they are on fresh clean towels which i will change daily.
I will keep you informed.
Thank you for your advice.
