Yes they will
Female gerbils are called does, the males are called bucks, a baby is called a pup, and a group of them is called a clan or a horde.
Gerbils only eat there pups if something is seriously wrong. (Dehydration, sick or injured pups, ect.) This not only applies to the mother, but also the father. Gerbil's make great dads.
Gerbils can have up to 13 or more pups in a litter! Quite a range, but 6-8 is the average.
Gerbils can have a litter about every 5 weeks. Gerbils mate right after the birth of a litter, and the mother can prolong the pregnancy to up to 40 days if she is nursing. A gerbil will produce about 4-5 pups on average per litter, but can have up to 12! With about 10 litters per year with no break, that means about 50 gerbil pups a year! They are rather prolific breeders. :]
they will if you don't take the male gerbil out of the cage after around less than a two weeks because if they mate after the female gerbil has her pups than they will mate again and she will not take care of the first litter of pups.
NO. Gerbils have 4-6 pups in each litter and can have regular litters so if you are going to breed them you have to know what you will do with the litter afterwards.
no. when the pups are born the non pregnant gerbil will kill the pups and most likely attemp or actually kill the mother too. but if the mother dies in birth the other gerbil may adopt the pups. take it from someone who knows. I disagree, if two females are raised together for a long period of time, they can be kept together if one has pups. I have raised gerbils a long time and usually the 2 females will raise the pups together.
Gerbil mothers should be kept either alone with their pups or with the father and the pups. NEVER put two females together if one is pregnant or nursing, as the other female will most likely get defensive and kill the litter. This goes even for gerbils who get along really well. The only instance you can keep two females in with a litter is if the other pup is a female from the previous litter.
There can be anywhere from 1-8 in a litter of pups although 12 pups have been reported. (One of ours had this abnormally large litter). If there are only 1 or 2 pups you risk the mother's milk not coming in. If you're trying to breed gerbils please read up on them. There are already too many backyard gerbil breeders and it's hurting their species so here are some good credible sites: http://www.egerbil.com http://www.gerbilcare.com http://www.agsgerbils.org
Gerbils will only eat their babies if the pup is dead, if there is not enough resources, such as water and food, or space, or if the mother is stressed. If there is another gerbil in the tank, other than the mother and the father or an older sibling, that gerbil might also eat the pups as a territorial issue. their spine will start to stick out and they will act very weak. there might be terms of eating alot, fighting with the male, sleeping alot,getting really fat, and not wanting to be held. so if you think your gerbil is pregnant then feel it's lower stomach .. and you may want to leave your gerbil alone this will cause allot of stress to her if you hold her often..
no a gerbil pup needs its mothers milk to survive when it is young
Gerbil mothers are usually quite tough with their offspring so a couple of scratches is normal, it would probably be an accident and she will tend to it. If it is more serious it could be she rejected the pup for whatever reason. If that's the case just leave her to it - or you can do the 24hr job of hand rearing the pup. Trust me, my gerbil had 5 pups, she rejected one and it died- don't take any dead pups away, mum will sort it- and another had a large scratch on his tummy but its cleared up now.
