I have 39 from 19 ewes. These Lleyns are a brilliant breed. Milk like dairy cows, top mothers and finish on grass at around 40-42kg.
Bit difficult to follow your thoughts on your poultry. If your selling pol at £10 for utility breeds your selling to cheap.
I breed utility and my bird are £25 each at POL.
You need to break your birds into 3 groups of different ages, so as one lot stops laying another lot start.
