so far ma strategy in less animals ...I had to much all dispached...and often I paid for animals and have not enough to feed them...
Some referrals are taking time from what I see I am still level 6 but there is a way to get past level 6 but it takes a few days to do it. You have to collect your Bonus every 8 hours and after 9 collections you will move to the next level. Same for higher levels I think but I am not sure.
Right now at level 6 I go with 4 Mallards, 1 Spotted goat and a Grey Rabbit. I have upgraded all of my food and water to highest level. I check back in every 3 - 4 hours and collect and repurchase animals and food. This way the goat gets enough food. Only collect the dead animals and let the other set until dead. I can get collections from 5 collections of ducks and rabbits while the goat matures and dies. This is a good return on my investment so far.
I started the same tactics last nigh with one goat and the rest are grey rabbits.
I also had pushed the storage levels to the maximum (for water, carrots and hay) and so far it seems indeed a good strategy.
